5cf6267915 staging: greybus: light: check the correct value of delay_on
When checking the value of delay_on to set the channel as active, it was
checked the pointer and not the value, as it should be.

Fixes: cc43368a3c ("greybus: lights: Control runtime pm suspend/resume on AP side")

dc875c7790 staging: greybus: light: check delay_{on|off} before use
Even though we trust leds core that the pointers should be valid, we are
safer to check delay_{on|off} before use.

Also, this avoid a smatch warning:
drivers/staging/greybus/light.c:484 gb_blink_set()
warn: variable dereferenced before check 'delay_on' (see line 476)

VCHIQ: Make service closure fully synchronous (drv)

This is one half of a two-part patch, the other half of which is to
the vchiq_lib user library. With these patches, calls to
vchiq_close_service and vchiq_remove_service won't return until any
associated callbacks have been delivered to the callback thread.

VCHIQ: Add per-service tracing

The new service option VCHIQ_SERVICE_OPTION_TRACE is a boolean that
toggles tracing for the specified service.

This commit also introduces vchi_service_set_option and the associated
option VCHI_SERVICE_OPTION_TRACE.

vchiq: Make the synchronous-CLOSE logic more tolerant

vchiq: Move logging control into debugfs

vchiq: Take care of a corner case tickled by VCSM

Closing a connection that isn't fully open requires care, since one
side does not know the other side's port number. Code was present to
handle the case where a CLOSE is sent immediately after an OPEN, i.e.
before the OPENACK has been received, but this was incorrectly being
used when an OPEN from a client using port 0 was rejected.

(In the observed failure, the host was attempting to use the VCSM
service, which isn't present in the 'cutdown' firmware. The failure
was intermittent because sometimes the keepalive service would
grab port 0.)

This case can be distinguished because the client's remoteport will
still be VCHIQ_PORT_FREE, and the srvstate will be OPENING. Either
condition is sufficient to differentiate it from the special case
described above.

vchiq: Avoid high load when blocked and unkillable

vchiq: Include SIGSTOP and SIGCONT in list of signals not-masked by vchiq to allow gdb to work

vchiq_arm: Complete support for SYNCHRONOUS mode

vchiq: Remove inline from suspend/resume

vchiq_arm: Two cacheing fixes

1) Make fragment size vary with cache line size
Without this patch, non-cache-line-aligned transfers may corrupt
(or be corrupted by) adjacent data structures.

Both ARM and VC need to be updated to enable this feature. This is
ensured by having the loader apply a new DT parameter -
cache-line-size. The existence of this parameter guarantees that the
kernel is capable, and the parameter will only be modified from the
safe default if the loader is capable.

2) Flush/invalidate vmalloc'd memory, and invalidate after reads

vchiq: fix NULL pointer dereference when closing driver

                err(1, "open failed");
        (void)close(fd);

The rtl871 driver declared an enum for representing LED states. The enum

In order to avoid a possible future collision LED_ON was changed to

8681a1d47b Fixes: 3d44a78f0d8b ("staging: rtl8712: Remove unnecessary 'else'")
An "unnecessary" 'else' was removed due to complains from checkpatch.pl
as it is preceded by a 'return', however the 'else' branch is necessary
as an earlier branch of the 'if' falls through. By removing the 'else',
that route now hits the 'break' and the 'while' loop exits prematurely.

This commit reverts that change and puts the original 'else' back in
place.
