[PATCH][next] drm/rockchip: lvds: ensure ret is assigned before checking for an error
From: Colin King <hidden>

From: Colin Ian King <redacted>
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")
