Subject: drm/tilcdc: panel: Set return value explicitly
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=12778fc14301cf24d79cd89b0129874c319d0a38;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/tilcdc: panel: Set return value explicitly

Instead of setting an initial value for the return code, set it explicitly
on each error path. This is just a cosmetic cleanup, as preparation for the
enable GPIO support.
