[PATCH] drm/bridge: fix odd_ptr_err.cocci warnings

[kbuild test robot]

drivers/gpu/drm/bridge/cdns-dsi.c:980:5-11: inconsistent IS_ERR and PTR_ERR on line 981.

 PTR_ERR should access the value just tested by IS_ERR

Semantic patch information:
 There can be false positives in the patch case, where it is the call to
 IS_ERR that is wrong.
