The debugging code in the following ifdef land - QL_ALL_DUMP - QL_REG_DUMP - QL_DEV_DUMP - QL_CB_DUMP - QL_IB_DUMP - QL_OB_DUMP becomes unnecessary because, - Device status and general registers can be obtained by ethtool. - Coredump can be done via devlink health reporter. - Structure related to the hardware (struct ql_adapter) can be obtained by crash or drgn.

With force_coredump module parameter set, devlink health dump will reset the MPI RISC first which takes 5 secs to be finished. Note that only NIC function that owns the firmware can do the force_dumping. Otherwise devlink will receive an EPERM error. Signed-off-by:

Stop calling ql_release_all in qlge_init_device and free things one step at a time. struct qlge_adapter *qdev is now a private structure of struct devlink and memset is not necessary. Link: https://lore.kernel.org/patchwork/patch/1321092/#1516928Suggested-by:

Initialize devlink health dump framework for the qlge driver so the coredump could be done via devlink. struct qlge_adapter is now used as the private data structure of struct devlink so it could exist independently of struct net_device and devlink reload could be supported in the future. The private data of PCIe driver now points to qlge_adapter. Since devlink_alloc will zero out struct qlge_adapter, memset in qlge_init_device is not necessary. Signed-off-by:

To avoid namespace clashes with other qlogic drivers and also for the sake of naming consistency, use the "qlge_" prefix as suggested in drivers/staging/qlge/TODO, - For existing ql_ prefix, sed -i "s/ql_/qlge_/g" *.{c,h} - for structs not having a prefix 1. get a list of structs grep "struct.*{" qlge. 2. add qlge_ for each struct, e.g., sed -i "s/ib_ae_iocb_rsp/qlge_ib_ae_iocb_rsp/g" *.{c,h} Link: https://lore.kernel.org/patchwork/patch/1318503/#1516131Suggested-by: -

Playing audio with PulseAudio and the bcm2835-pcm driver results in distorted sound. Timer-based scheduling does not properly work with bcm2835-pcm since configuring PulseAudio with tsched=0 avoids this problem. Setting the SNDRV_PCM_INFO_BATCH flag prevents PulseAudio to use timer-based scheduling by default. Settings this flag makes audio works out of the box.

During the driver refactor, a regression broke the logic inside hi6421_spmi_regulator_get_optimum_mode(). Basically, if a LDO has eco_uA == 0, it doesn't support economic mode. So, it should return REGULATOR_MODE_NORMAL. If economic mode is supported, it can return either REGULATOR_MODE_IDLE or REGULATOR_MODE_NORMAL, depending on the load current. Signed-off-by:

The original driver, which can be seen at commit 42f24d9d ("staging: regulator: add a regulator driver for HiSilicon 6421v600 SPMI PMIC") had a complex logic to ensure that there won't be multiple power enable/disable commands running at the same time. At the original logic, it were ensured that: - a next power up/down would wait for at least the on/off period; - an extra delay would be granted. It turns that such extra delay has a value of zero, but it was relying on gettimeofday() call, which can take some time. This was later simplified, but there are still some possible issues. In order to avoid that, let's simply add a delay to wait for the power up line to stabilize after powering up a device. Signed-off-by:

The interrupt support for Advantech PCI-1730 currrently supports only rising edge inputs for the trigger sources. Each of four interrupt sources (each with its own Comedi subdevice) can be set to trigger on either a rising edge or a falling edge. Add support for choosing the edge during set-up of the asynchronous command for the subdevice, using the `CR_INVERT` bit of `scan_begin_arg` to indicate falling edge when set, or rising edge when clear. Also allow the `CR_EDGE` bit to be set, but ignore it. All other bits of `scan_begin_arg` must be zero. Signed-off-by:

On the Advantech PCI-1730, four digital inputs (DI0, DI1, IDI0 and IDI1) can be used as external interrupt sources. Each input can be programmed to latch an interrupt bit on either a rising edge or a falling edge (but not both). Add a new Comedi subdevice for each interrupt source, supporting the asynchronous command interface. Subdevices 5, 6, 7 and 8 are for interrupt sources DI0, DI1, IDI0 and IDI1. They each write the state of 16 digital inputs to the subdevice's data buffer each time the corresponding interrupt occurs. (For DI0 and DI1, use the 16 non-isolated digital inputs. For IDI0 and IDI1, use the 16 isolated digital inputs.) Currently, only rising edge triggers are supported. Support could be added for the PCI-1733 and PCI-1736. Signed-off-by:

On the ADLink PCI-7230, digital input channels 0 and 1 can be used as external interrupt sources. A rising edge on each input latches a corresponding local interrupt input of the PCI interface chip. Writing a "clear IRQ" register clears both latches. Add a new Comedi subdevice for each interrupt source, supporting the asynchronous command interface. This writes the state of the 16 digital inputs to the subdevice's data buffer each time the corresponding interrupt occurs. This could be adapted to support the PCI-7233, PCI-7432 and PCI-7433 boards too. They all have two interrupt sources, although for PCI-7233 each interrupt source is triggered by a change of state of 16 digital inputs (0-15 and 16-31). The "clear IRQ" register is at a different offset for some boards. Signed-off-by:

The custom regulatory ruleset in the rtl8723bs driver lists an incorrect number of rules: one too many. This results in an out-of-bounds access, as detected by KASAN. This was possible thanks to the newly added support for KASAN on ARMv7. Fix this by filling in the correct number of rules given.
