[PATCH][next] drm/rockchip: lvds: ensure ret is assigned before checking for an error

From: Colin Ian King <colin.king at canonical.com>

Currently there are two places where the return status in ret is being
checked for an error however the assignment of ret has been omitted
making the checks redundant.  Fix this by adding in the missing assignments
of ret.

Addresses-Coverity: ("Logically dead code")
Fixes: cca1705c3d89 ("drm/rockchip: lvds: Add PX30 support")
