Subject: drm/sun4i: Fix error handling
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6c08d7ab23dd07c046e8de1520073053bdc76ae2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/sun4i: Fix error handling

'sun4i_layers_init()' returns an error pointer in case of error, not
NULL. So test it with IS_ERR.
