Tomi Valkeinen 6bec5b0b70 drm/bridge: tc358768: Fix use of uninitialized variable
[ Upstream commit a2d9036615 ]

smatch reports:

drivers/gpu/drm/bridge/tc358768.c:223 tc358768_update_bits() error: uninitialized symbol 'orig'.

Fix this by bailing out from tc358768_update_bits() if the
tc358768_read() produces an error.

Fixes: ff1ca6397b ("drm/bridge: Add tc358768 driver")
