commit 96be39ab upstream. Commit 30a70b02 ("usb: musb: fix obex in g_nokia.ko causing kernel panic") attempted to fix runtime PM handling for PHYs that are on the I2C bus. Commit 3063a12b ("usb: musb: fix PHY power on/off") then changed things around to enable of PHYs that rely on runtime PM. These changes however broke idling of the PHY and causes at least 100 mW extra power consumption on omaps, which is a lot with the idle power consumption being below 10 mW range on many devices. As calling phy_power_on/off from runtime PM calls in the USB causes complicated issues with I2C connected PHYs, let's just let the PHY do it's own runtime PM as needed. This leaves out the dependency between PHYs and USB controller drivers for runtime PM. Let's fix the regression for twl4030-usb by adding minimal runtime PM support. This allows idling the PHY on disconnect. Note that we are changing to use standard runtime PM handling for twl4030_phy_init() as that function just checks the state and does not initialize the PHY. The PHY won't get initialized until in twl4030_phy_power_on(). Fixes: 30a70b02 ("usb: musb: fix obex in g_nokia.ko causing kernel panic") Fixes: 3063a12b ("usb: musb: fix PHY power on/off") Acked-by:

commit 85601b8d upstream. Commit 249751f2 ("usb: phy: twl4030-usb: poll for ID disconnect") added twl4030_id_workaround_work() to deal with lost interrupts after ID pin goes down. Looks like commit f1ddc24c ("usb: phy: twl4030-usb: remove *set_suspend* and *phy_init* ops") changed things around for the generic phy framework, and delayed work no longer got called except initially during boot. The PHY connect and disconnect interrupts for twl4030-usb are not working after disconnecting a USB-A cable from the board, and the deeper idle states for omap are blocked as the USB controller stays busy. The issue can be solved by calling delayed work from twl4030_usb_irq() when ID pin is down and the PHY is not asleep like we already do in twl4030_id_workaround_work(). But as both twl4030_usb_irq() and twl4030_id_workaround_work() already do pretty much the same thing, let's call twl4030_usb_irq() from twl4030_id_workaround_work() instead of adding some more duplicate code. We also must call sysfs_notify() only when we have an interrupt and not from the delayed work as notified by Grazvydas Ignotas <notasas@gmail.com>.

commit 9ce9ec95 upstream. The PHY configuration is stored in an opaque "config" field, but when allocating the structure, its proper size needs to be known. In the case of UTMI, the proper structure is tegra_utmip_config of which a local variable already exists, so we can use that to obtain the size from. Fixes the following warning from the sparse checker: drivers/usb/phy/phy-tegra-usb.c:882:17: warning: expression using sizeof(void) Fixes: 81d5dfe6 (usb: phy: tegra: Read UTMIP parameters from device tree) Signed-off-by:

commit 049255f5 upstream. Sierra Wireless Direct IP devices using the 68A3 product ID can be configured for modes including a CDC ECM class function. The known example uses interface numbers 12 and 13 for the ECM control and data interfaces respectively, consistent with CDC MBIM function interface numbering on other Sierra devices. It seems cleaner to restrict this driver to the ff/ff/ff vendor specific interfaces rather than increasing the already long interface number blacklist. This should be more future proof if Sierra adds more class functions using interface numbers not yet in the blacklist. Signed-off-by:

commit 63a901c0 upstream. This reverts commit 73228a05 ("USB: option,zte_ev: move most ZTE CDMA devices to zte_ev"). Move the IDs of the devices that were previously driven by the option driver back to that driver. As several users have reported, the zte_ev driver is causing random disconnects as well as reconnect failures. A closer analysis of the zte_ev setup code reveals that it consists of standard CDC requests (SET/GET_LINE_CODING and SET_CONTROL_LINE_STATE) but unfortunately fails to get some of those right. In particular, as reported by Liu Lei, it fails to lower DTR/RTS on close. It also appears that the control requests lack the interface argument. Note that the zte_ev driver is based on code (once) distributed by ZTE that still appears to originally have been reverse-engineered and bolted onto the generic driver. Since line control is already handled properly by the option driver, and the SET/GET_LINE_CODING requests appears to be redundant (amounts to a SET 9600 8N1), this is a first step in ultimately removing the redundant zte_ev driver. Note that AC2726 had already been moved back to option, and that some IDs were in the device table of both drivers prior to the commit being reverted. Reported-by:

commit f0e4cba2 upstream. Do not log normal interrupt-urb shutdowns as errors. The option driver has always been logging any nonzero interrupt-urb status as an error, including when the urb is killed during normal operation. Commit 9096f1fb ("USB: usb_wwan: fix potential NULL-deref at resume") moved the interrupt urb submission from port probe and release to open and close, thus potentially increasing the number of these false-positive error messages dramatically.

commit 9ef7db7f upstream. Commit 0244756e ("ufs: sb mutex merge + mutex_destroy") introduces deadlocks in ufs_new_inode() and ufs_free_inode(). Most callers of that functions acqure the mutex by themselves and ufs_{new,free}_inode() do that via lock_ufs(), i.e we have an unavoidable double lock. The patch proposes to resolve the issue by making sure that ufs_{new,free}_inode() are not called with the mutex held. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

commit 7128039f upstream. Current definition of TLBTEMP_BASE_2 is always 32K above the TLBTEMP_BASE_1, whereas fast_second_level_miss handler for the TLBTEMP region analyzes virtual address bit (PAGE_SHIFT + DCACHE_ALIAS_ORDER) to determine TLBTEMP region where the fault happened. The size of the TLBTEMP region is also checked incorrectly: not 64K, but twice data cache way size (whicht may as well be less than the instruction cache way size). Fix TLBTEMP_BASE_2 to be TLBTEMP_BASE_1 + data cache way size. Provide TLBTEMP_SIZE that is a greater of doubled data cache way size or the instruction cache way size, and use it to determine if the second level TLB miss occured in the TLBTEMP region. Practical occurence of page faults in the TLBTEMP area is extremely rare, this code can be tested by deletion of all w[di]tlb instructions in the tlbtemp_mapping region. Signed-off-by:
