drm/panthor: Always wait after sending a command to an AS

Browse source

[ Upstream commit d2c6fde56d ]

There's currently no situation where we want to issue a command to an
AS and not wait for this command to complete. The wait is either
explicitly done (LOCK, UNLOCK) or it's missing (UPDATE). So let's
turn write_cmd() into as_send_cmd_and_wait() that has the wait after
a command is sent.

v2:
- New patch

v3:
- Collect R-b

v4:
- No changes
