In case of error, the function of_drm_find_bridge() returns NULL pointer not ERR_PTR().
Such information is helpful.
The IS_ERR() test in the return value check should be replaced with NULL test.
* Would you like to convert this description into an imperative wording?
* Please fix the patch subject according to a function name.
* How do you think about to add the tag “Fixes” to the commit message because of an adjustment for the error detection?
