[PATCH -next] drm/mcde: dsi: Fix return value check in dev_err()

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

 



In case of error, the function of_drm_find_bridge() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.
