Subject: [PATCH] drm/vc4: hdmi: Warn if writing to an unknown HDMI register
|
|
|
|
The VC4 HDMI driver has a bunch of accessors to read from a register.
|
|
The read accessor was warning when accessing an unknown register, but
|
|
the write one was just returning silently.
|
|
|
|
Let's make sure we warn also when writing to an unknown register.
