We know that it is a bad idea to explicitly enable IRQs when we don't
don't know if they were already off before we disabled, so switch to the
save _irqsave and _irqrestore functions.
Ultimately, we need to review places in the Greybus drivers where IRQs
are disabled and remove unnecessary instances. This is only an interim
step.
This code will never run from hard irq context, as it is already taking
mutex in the path.

The greybus SVC core handles events from the SVC serially today. In some
cases the SVC operations may take too long, for example trying to
activate a dummy interface. If another interface receives a mode-switch
mailbox event in that time, the SVC core wouldn't be able to process it
in quickly enough and bootrom driver will print following error:
bootrom 1-3.3.1: Timed out waiting for Interface Mode Switch from the Module
This can be reproduced easily by attaching a 2x2 module along with any
other normal module like camera or speaker, and doing a unipro_reset
from userspace.
The logs suggest this time to be around 6-7 seconds in most of the
cases. Attaching multiple modules with dummy interfaces may make this
worst.
Lets increase the timeout from 5 to 10 seconds for now, also add a FIXME
for the same.

gb_timesync_svc_teardown() is called from gb_timesync_svc_del() and issues a
command to a remote Interface to switch off its timers. The lock ordering
is TimeSync => Interface in this case. However gb_module_del() takes an
Interface lock then calls gb_interface_del() => gb_timesync_svc_del() in
this case the lock ordering is Interface => TimeSync.
This patch fixes by removing the taking of the Interface mutex in
gb_interface_timesync_do_something(). If an Interface is present in the

GB_TIMESYNC_STATE_INIT state, for example failure to issue a TimeSync
enable command to the SVC can and should legitimately call
gb_timesync_teardown() - at this point the state will be
GB_TIMESYNC_STATE_WAIT_SVC and it's legitimate and desirable to transition
to the INACTIVE state in this case. This patch fixes by removing the
restrictive and incorrect restriction on the transition to INACTIVE only

operation properly, with default values passed for the new necessary

We must make sure to zero the request structure sent across the wire, lest
