[PATCH -next] drm/exynos: mic: fix return value check in exynos_mic_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If of_graph_get_remote_node() fails, it returns NULL pointer, replaces
IS_ERR() check with NULL pointer check.

Fixes: dd8b6803bc49 ("exynos: drm: dsi: Attach in_bridge in MIC driver")
