Subject: [PATCH] drm/bridge: imx8mp-hdmi-pvi: Fix build warnings

Two separate build warnings were reported. One from an
uninitialized variable, and the other from returning 0
instead of NULL from a pointer.

Fixes: 059c53e877ca ("drm/bridge: imx: add driver for HDMI TX Parallel Video Interface")
Reported-by: [email protected]
Reported-by: kernel test robot <[email protected]>
