[PATCH] drm/mcde: dsi: Fix a return value check in mcde_dsi_bind()

[Markus Elfring]

> 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?

Markus
