In order to pass VHT parameters to wcn3680 we need to use a super-set of
the V1 data-structures with additional VHT parameters tacked on.
This patch adds the additional fields to the STA and BSS parameter
structures.
Since neither wcn3620 nor wcn3660 support VHT the size of the passed
message is fixed to the previous message length. Subsequent changes will
differentiate between wcn3620/wcn3660 and wcn3680 which does use the larger
message size.

IPQ8074 HW uses rproc with AHB as underlying hif layer.
Move rproc references from common core layer to target
hif layer. Remove IS_ENABLED check for CONFIG_REMOTEPROC
as it's not required anymore.
No functional changes. Compile tested only.

usb_kill_anchored_urbs()
Calls to usb_kill_anchored_urbs() after usb_kill_urb() on multiprocessor
systems create a race condition in which usb_kill_anchored_urbs() deallocates
the URB before the completer callback is called in usb_kill_urb(), resulting
in a use-after-free.
To fix this, add proper lock protection to usb_kill_urb() calls that can
possibly run concurrently with usb_kill_anchored_urbs().

The wilc_wfi_init_mon_int() forgets to clean up resource when
register_netdevice() failed. Add the missed call to fix it.
And the return value of netdev_priv can't be NULL, so remove

Commit bff1cef5f23a ("clk: tegra: Don't enable already enabled PLLs")
added checks to avoid enabling PLLs that have already been enabled by
the bootloader. However, the PLL_E configuration inherited from the
bootloader isn't necessarily the one that is needed for the kernel.
This can cause SATA to fail like this:
[ 5.310270] phy phy-sata.6: phy poweron failed --> -110
[ 5.315604] tegra-ahci 70027000.sata: failed to power on AHCI controller: -110
[ 5.323022] tegra-ahci: probe of 70027000.sata failed with error -110
Fix this by always programming the PLL_E. This ensures that any mis-
configuration by the bootloader will be overwritten by the kernel.

The overflow happens, because in btree_readpage_end_io_hook() we assume
that we have found a 4 byte checksum instead of the real possible 32
bytes we have for the checksums.

By default, PCI drivers with runtime PM enabled will skip the calls
to suspend and resume on system PM. For this driver, we don't want
that, as we need to perform additional steps for system PM to work
properly on all systems. So instruct the PM core to not skip these
calls.

NULL pointer dereference is observed while exporting the dmabuf but
failed to allocate the 'struct file' which results into the dropping of

is ending up in dma_buf_release() and accessing the uninitialzed
dentry->d_fsdata.

We found a Mic detection issue on many Lenovo laptops, those laptops
belong to differnt models and they have different audio design like
internal mic connects to the codec or PCH, they all have this problem,
the problem is if plugging a headset before powerup/reboot the
machine, after booting up, the headphone could be detected but Mic
couldn't. If we plug out and plug in the headset, both headphone and
Mic could be detected then.
Through debugging we found the codec on those laptops are same, it is
alc257, and if we don't disable the 3k pulldown in alc256_shutup(),
the issue will be fixed. So far there is no pop noise or power
consumption regression on those laptops after this change.

This patch adds a new initialization function:
can_rx_offload_add_manual()
It should be used to add support rx-offload to a driver, if the callback
mechanism should not be used. Use e.g. can_rx_offload_queue_sorted() to queue
skbs into rx-offload.

Some SPI host controllers do not support full-duplex SPI and are
marked as such via the SPI_CONTROLLER_HALF_DUPLEX controller flag.
For such controllers use half duplex transactions but retain full
duplex transactions for the controllers that can handle those.

Since commits
653ee35ce6d5 ("can: hi311x: remove custom DMA mapped buffer")
Fixes: df58525df395 ("can: mcp251x: remove custom DMA mapped buffer")
both the hi3111x and the mcp251x driver don't make use of the DMA API
any more. So we can safely remove the HAS_DMA dependency.
While we're here, remove the unneeded CAN_DEV and SPI dependencies from
the CAN_HI311X symbol, as the parent menus already have these
dependencies.

This patch adds the support of the rx/tx errors CAN counters to the
driver of the PCAN-USB PC-CAN interface from PEAK-System GmbH.
The PCAN-USB is capable of giving back the values of the rx/tx errors
counters, to provide more details and statistics to the linux-can layer.
Getting these values allows the driver to better tune CAN_ERR_CRTL_TX_xxx
and CAN_ERR_CRTL_RX_xxx bits in case of the interface enters any
CAN_STATE_ERROR_xxx state.

Drivers using legacy power management .suspen()/.resume() callbacks have to
manage PCI states and device's PM states themselves. They also need to take
care of standard configuration registers.
Switch to generic power management framework using a single "struct dev_pm_ops"
variable to take the unnecessary load from the driver. This also avoids the
need for the driver to directly call most of the PCI helper functions and
device power state control functions, as through the generic framework PCI Core
takes care of the necessary operations, and drivers are required to do only
device-specific jobs.
