Fix this bug: drivers/media/platform/mtk-vcodec/vdec_drv_if.c:38 vdec_if_init() info: ignoring unreachable code. With is indeed a real problem that prevents the driver to work! While here, also remove an used var, as reported by smatch: drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_pm.c: In function 'mtk_vcodec_init_dec_pm': drivers/media/platform/mtk-vcodec/mtk_vcodec_dec_pm.c:29:17: warning: variable 'dev' set but not used [-Wunused-but-set-variable] struct device *dev; ^~~ Signed-off-by: Mauro Carvalho Chehab <redacted>
