-Subject: drm/edid: Fix a missing-check bug in drm_load_edid_firmware()
-
-In drm_load_edid_firmware(), fwstr is allocated by kstrdup(). And fwstr
-is dereferenced in the following codes. However, memory allocation
-functions such as kstrdup() may fail and returns NULL. Dereferencing
-this null pointer may cause the kernel go wrong. Thus we should check
-this kstrdup() operation.
-Further, if kstrdup() returns NULL, we should return ERR_PTR(-ENOMEM) to
-the caller site.
