diag: Fix race condition in diagchar driver

diag driver maintains socket logging process in global driver
structure which is manipulated in switch_logging and in close
file_operation.
There is a possibility of race while clearing the socket logging
process in close operation and sending signal in switch_logging
operation. Adding lock to serialize the two operations.

msm_serial_hs: Rx discard flush timeout

While configuring the uart buadrate using set_termios
function, timeout is occuring for rx discard flush
operation. This is due to the driver is waiting for
less time for the DMA call back to occur after programing
the DMA register with the discard flush command.

To overcome this issue increased the timeout to 300ms.

mfd: wcd9xxx: Let system suspend and lock it later

When wcd9xxx codec receives IRQ, codec driver acquires suspend lock to
prevent system from entering suspend and waits until either system is
already awake or is awoken.
However if power management interface is already in the middle of calling
suspend chains, codec cannot lock suspend.
For this case, let the power management interface to proceed suspend and
make codec driver not to handle IRQ for now so unhandled IRQ would raise
shortly again.

cfg80211/nl80211: add API for MAC address ACLs

Add API to enable drivers to implement MAC address based
access control in AP/P2P GO mode. Capable drivers advertise
this capability by setting the maximum number of MAC
addresses in such a list in wiphy->max_acl_mac_addrs.

An initial ACL may be given to the NL80211_CMD_START_AP
command and/or changed later with NL80211_CMD_SET_MAC_ACL.

Black- and whitelists are supported, but not simultaneously.

msm: bam_dmux: trigger modem subsystem restart in case of timeout

If bam_dmux times out waiting for a power collapse protocol response from
the modem, bam_dmux assumes the modem has crashed and will disable itself
until the subsystem restart callback is triggered.

restarts regardless of its current state so that the restart callback is
always triggered.

power: pm8921-bms: Fix SOC fluctuations at 100%

It is observed that the SOC can oscillate between 100-99-100
based on OCV updates after EOC (it is possible that there are
multiple varying OCV updates as the battery settles down).
Prevent this by avoiding the SOC to increase if it has dropped
and not charging.

While handling this scenario make sure that we do not scale
when soc = 100 and charging.
