commit 997f16bd upstream. Current clamping of a normal divider allows a value < 1 to be valid. A divider of < 1 would actually only be possible if we had a PLL... So this patch clamps the divider to 1. Fixes: 41691b88 ("clk: bcm2835: Add support for programming the audio domain clocks") Signed-off-by:

commit 6727f086 upstream. bcm2835_pll_off is currently assigning CM_PLL_ANARST to the control register, which may lose the other bits that are currently set by the clock dividers. It also now locks during the read/modify/write cycle of both registers. Fixes: 41691b88 ("clk: bcm2835: Add support for programming the audio domain clocks") Signed-off-by:

commit e708b383 upstream. In poweroff, we set the reset bit and the power down bit, but only managed to unset the reset bit for poweron. This meant that if HDMI did -EPROBE_DEFER after it had grabbed its clocks, we'd power down the PLLH (that had been on at boot time) and never recover. Signed-off-by:

commit e7387da5 upstream. Commit 0b89e9aa (cpuidle: delay enabling interrupts until all coupled CPUs leave idle) rightfully fixed a regression by letting the coupled idle state framework to handle local interrupt enabling when the CPU is exiting an idle state. The current code checks if the idle state is coupled and, if so, it will let the coupled code to enable interrupts. This way, it can decrement the ready-count before handling the interrupt. This mechanism prevents the other CPUs from waiting for a CPU which is handling interrupts. But the check is done against the state index returned by the back end driver's ->enter functions which could be different from the initial index passed as parameter to the cpuidle_enter_state() function. entered_state = target_state->enter(dev, drv, index); [ ... ] if (!cpuidle_state_is_coupled(drv, entered_state)) local_irq_enable(); [ ... ] If the 'index' is referring to a coupled idle state but the 'entered_state' is *not* coupled, then the interrupts are enabled again. All CPUs blocked on the sync barrier may busy loop longer if the CPU has interrupts to handle before decrementing the ready-count. That's consuming more energy than saving.

commit c998c078 upstream. Currently the 'registered' member of the cpuidle_device struct is set to 1 during cpuidle_register_device. In this same function there are checks to see if the device is already registered to prevent duplicate calls to register the device, but this value is never set to 0 even on unregister of the device. Because of this, any attempt to call cpuidle_register_device after a call to cpuidle_unregister_device will fail which shouldn't be the case. To prevent this, set registered to 0 when the device is unregistered. Fixes: c878a52d (cpuidle: Check if device is already registered) Signed-off-by:

commit 7a18afe8 upstream. On ads7828 the internal reference defaults to off upon power up. When using internal reference, it needs to be turned on and the voltage needs to settle before normal conversion cycle can be started. Hence perform a dummy read in the probe to enable the internal reference allowing the voltage to settle before performing a normal read. Without this fix, the first read from the ADC when using internal reference always returns incorrect data. Signed-off-by:

commit 5e3ca2b3 upstream. Commit 6261b06d ("regulator: Defer lookup of supply to regulator_get") moved the regulator supplies lookup logic from the regulators registration to the regulators get time. Unfortunately, that changed the behavior of the regulator core since now a parent supply with a child regulator marked as always-on, won't be enabled unless a client driver attempts to get the child regulator during boot. This patch tries to resolve the parent supply for the already registered regulators each time that a new regulator is registered. So the regulators that have child regulators marked as always on will be enabled regardless if a driver gets the child regulator or not. That was the behavior before the mentioned commit, since parent supplies were looked up at regulator registration time instead of during child get. Since regulator_resolve_supply() checks for rdev->supply, most of the times it will be a no-op. Errors aren't checked to keep the possible out of order dependencies which was the motivation for the mentioned commit. Also, the supply being available will be enforced on regulator get anyways in case the resolve fails on regulators registration.

commit 78cbccd3 upstream. When KDUMP is triggered the driver first talks to the firmware in INTX mode, but the adapter firmware is still in MSIX mode. Therefore the first driver command hangs since the driver is waiting for an INTX response and firmware gives a MSIX response. If when the OS is installed on a RAID drive created by the adapter KDUMP will hang since the driver does not receive a response in sync mode. Fixed by: Change the firmware to INTX mode if it is in MSIX mode before sending the first sync command. Signed-off-by:

commit fc4bf75e upstream. Typically under error conditions, it is possible for aac_command_thread() to miss the wakeup from kthread_stop() and go back to sleep, causing it to hang aac_shutdown. In the observed scenario, the adapter is not functioning correctly and so aac_fib_send() never completes (or time-outs depending on how it was called). Shortly after aac_command_thread() starts it performs aac_fib_send(SendHostTime) which hangs. When aac_probe_one /aac_get_adapter_info send time outs, kthread_stop is called which breaks the command thread out of it's hang. The code will still go back to sleep in schedule_timeout() without checking kthread_should_stop() so it causes aac_probe_one to hang until the schedule_timeout() which is 30 minutes. Fixed by: Adding another kthread_should_stop() before schedule_timeout() Signed-off-by:

commit 07beca2b upstream. aac_fib_send has a special function case for initial commands during driver initialization using wait < 0(pseudo sync mode). In this case, the command does not sleep but rather spins checking for timeout.This loop is calls cpu_relax() in an attempt to allow other processes/threads to use the CPU, but this function does not relinquish the CPU and so the command will hog the processor. This was observed in a KDUMP "crashkernel" and that prevented the "command thread" (which is responsible for completing the command from being timed out) from starting because it could not get the CPU. Fixed by replacing "cpu_relax()" call with "schedule()" Signed-off-by:

commit c18d8f50 upstream. A number of new laptops have been delivered with only a single antenna. In principle, this is OK; however, a problem arises when the on-board EEPROM is programmed to use the other antenna connection. The option of opening the computer and moving the connector is not always possible as it will void the warranty in some cases. In addition, this solution breaks the Windows driver when the box dual boots Linux and Windows. A fix involving a new module parameter has been developed. This commit adds the new parameter and implements the changes needed for the driver. Signed-off-by:

An issue is reported that after restart work, survey dump data do not contain in-use (SURVEY_INFO_IN_USE) info for operating channel. During reconfigure, since mac80211 already has valid channel context for given radio, channel context iteration return num_chanctx > 0. Hence rx_channel is always NULL.

Writing a new value to the LED device while holding the Start button and running jstest is sufficient to reproduce this bug. An event will come through with the Start button released. Xboxdrv also won't attempt to read controller input from a packet where byte 0 is non-zero. It also checks that byte 1 is 0x14, but that value differs between wired and wireless controllers and this code is shared by both. I think just checking byte 0 is enough to eliminate unwanted packets. The following are some examples of 3-byte status packets I saw: 01 03 02 02 03 00 03 03 03 08 03 00 Signed-off-by:

commit affa80bd upstream. When running a 32-bit userspace on a 64-bit kernel, the UI_SET_PHYS ioctl needs to be treated with special care, as it has the pointer size encoded in the command. Signed-off-by:

commit d3030d11 upstream. The ak4642 driver is using a regmap cache sync to restore the configuration of the chip on resume but (as Peter observed) does not actually define a register cache which means that the resume is never going to work and we trigger asserts in regmap. Fix this by enabling caching. Reported-by:

commit 01d6e087 upstream. Commit c8f33d0b ("affs: kstrdup() memory handling") checks if the kstrdup function returns NULL due to out-of-memory condition. However, if we are remounting a filesystem with no change to filesystem-specific options, the parameter data is NULL. In this case, kstrdup returns NULL (because it was passed NULL parameter), although no out of memory condition exists. The mount syscall then fails with ENOMEM. This patch fixes the bug. We fail with ENOMEM only if data is non-NULL. The patch also changes the call to replace_mount_options - if we didn't pass any filesystem-specific options, we don't call replace_mount_options (thus we don't erase existing reported options).
