Subject: [PATCH] drm/vc4: hdmi: Fix clock value used for validating
|
|
hdmi modes
|
|
|
|
We are using mode->crt_clock here which is filled by drm_mode_set_crtcinfo()
|
|
which is called right after .mode_valid.
|
|
|
|
Use mode->clock which is valid here.
|
|
|
|
Fixes: 624d93a4f0 ("drm/vc4: hdmi: Move clock calculation into its own function")
