MLK-19455 tick/nohz: Prevent bogus softirq pending warning
Commit
0a0e0829f990 ("nohz: Fix missing tick reprogram when interrupting an
inline softirq") got backported to stable trees and now causes the NOHZ
softirq pending warning to trigger. It's not an upstream issue as the NOHZ
update logic has been changed there.
The problem is when a softirq disabled section gets interrupted and on
return from interrupt the tick/nohz state is evaluated, which then can
observe pending soft interrupts. These soft interrupts are legitimately
pending because they cannot be processed as long as soft interrupts are
disabled and the interrupted code will correctly process them when soft
interrupts are reenabled.
Add a check for softirqs disabled to the pending check to prevent the
warning.

Currently the generic power domain suspend code pm_genpd_suspend_noirq
will try to power off a domain used by devices in genpd_sync_poweroff
if its status is not GPD_STATE_ACTIVE.
However, for power domains supporting multiple low power states, it may
already enter an intermediate low power state by runtime PM before system
suspend and the status is already GPD_STATE_POWER_OFF which results in
then the power domain stay at an intermediate low power state during
system suspend.
Let's give the power domain a chance to switch to the deepest state in
case it's already off but in an intermediate low power state.
Due to power domain is alway off, so no need to check device wakeup

Firmware returns proprietary error code when getting error in
fil_cmd_data_set or fil_cmd_data_get. Sometimes the vendor tool or
utilities which uses libnl may stuck in some commands when wl is down.
For example, issue "scan" command after issuing "down" command, the
"scan" command will be the blocking call and stuck as no response from
firmware. It is caused by that firmware returns BCME_NOTUP(-4) when wl
is down, but in Linux the -4 is -EINTR, so libnl catches the error and
not pass to upper layer.
Because of that, the driver should return Linux error code instead of the
proprietary error code, and the tools or utilities need to get the real
firmware error code by another command "bcmerrorstr" after receiving
the error.
