The driver uses platform_driver_probe() to obtain platform data
if any. However, that function is placed in the .init section so
it must be called upon driver module initialization.
The problem was reported by Fenguang Wu resulting in a kernel
oops because the .init section was already freed.

On Surface Pro, suspend to ram gives a NULL pointer dereference in

call is clearing carrier in mwifiex_usb suspend handler.
Since commit 1499d9f "mwifiex: don't drop carrier flag over suspend"

and PCIe drivers, I'm removing it in USB driver too. This also fixes
the bug for Surface Pro.

Bug 60815 - Interface hangs in mwifiex_usb
https://bugzilla.kernel.org/show_bug.cgi?id=60815
We have 4 bytes of interface header for packets delivered to SDIO
and PCIe, but not for USB interface.
In Tx AMSDU case, currently 4 bytes of garbage data is unnecessarily
appended for USB packets. This sometimes leads to a firmware hang,
because it may not interpret the data packet correctly.
Problem is fixed by removing this redundant headroom for USB.

For pcie8897, the hs_cfg cancel command (0xe5) times out when host
comes out of suspend. This is caused by an incompleted host sleep
handshake between driver and firmware.
Like SDIO interface, PCIe also needs to go through firmware power
save events to complete the handshake for host sleep configuration.
Only USB interface doesn't require power save events for hs_cfg.

In the following scenario the socket is corked:
If the first UDP packet is larger then the mtu we try to append it to the
write queue via ip6_ufo_append_data. A following packet, which is smaller
than the mtu would be appended to the already queued up gso-skb via
plain ip6_append_data. This causes random memory corruptions.
In ip6_ufo_append_data we also have to be careful to not queue up the
same skb multiple times. So setup the gso frame only when no first skb
is available.
This also fixes a shortcoming where we add the current packet's length to
cork->length but return early because of a packet > mtu with dontfrag set
(instead of sutracting it again).

on-stack variable "ee" and unmaps it if mapping of the new descriptor
succeeded.

are masked. However, unlike other blocks the MCP's attention is not masked

auto negotiation only when old Warpcore microcode was used (below D108).
This patch comes to generalize this by keep trying to restart KR link,

issue which source is a link-partner. As part of this change, the signal
detect is no longer a condition to apply the work-around to cover this new case.

The locking is needed, since the the internal buffer for the CAN frames is

When the dlc is closed, rfcomm_dev_state_change() tries to release the
port in the case it cannot get a reference to the tty. However this is
racy and not even needed.
Infact as Peter Hurley points out:
1. Only consider dlcs that are 'stolen' from a connected socket, ie.
reused. Allocated dlcs cannot have been closed prior to port
activate and so for these dlcs a tty reference will always be avail
in rfcomm_dev_state_change() -- except for the conditions covered by
#2b below.
2. If a tty was at some point previously created for this rfcomm, then
either
(a) the tty reference is still avail, so rfcomm_dev_state_change()
will perform a hangup. So nothing to do, or,
(b) the tty reference is no longer avail, and the tty_port will be
destroyed by the last tty_port_put() in rfcomm_tty_cleanup.
Again, no action required.
3. Prior to obtaining the dlc lock in rfcomm_dev_add(),
rfcomm_dev_state_change() will not 'see' a rfcomm_dev so nothing to
do here.
4. After releasing the dlc lock in rfcomm_dev_add(),
rfcomm_dev_state_change() will 'see' an incomplete rfcomm_dev if a
tty reference could not be obtained. Again, the best thing to do here
is nothing. Any future attempted open() will block on
rfcomm_dev_carrier_raised(). The unconnected device will exist until
released by ioctl(RFCOMMRELEASEDEV).
The patch removes the aforementioned code and uses the
tty_port_tty_hangup() helper to hangup the tty.

The SFC9120 MC firmware often takes longer than 20ms to reboot and
update the warm boot count in BIU_MC_SFT_STATUS_REG. A timeout of
250ms is very generous for an MC reboot.

Scheduling a reset following an MC reboot event before waiting for
reboot to complete results in a race that can lead to a state where
must_realloc_vis is false in efx_ef10_fini_dmaq() but the VIs have
been destroyed during the MC reboot.
To avoid MC errors when trying to remove VIs that do not exist, wait
for the MC reboot to complete before scheduling the reset.

Merge tag 'arm64-stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64
Pull ARM64 fixes from Catalin Marinas:
- Compat register fault reporting fix
- Documentation clarification on tagged pointers
- hwcap widened to 64-bit (user space already reading it as 64-bit)
* tag 'arm64-stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64:
arm64: Widen hwcap to be 64 bit
arm64: Correctly report LR and SP for compat tasks
arm64: documentation: tighten up tagged pointer documentation
arm64: Make do_bad_area() function static
Under arm64 elf_hwcap is a 32 bit quantity, but it is stored in
a 64 bit auxiliary ELF field and glibc reads hwcap as 64 bit.
This patch widens elf_hwcap to be 64 bit.
