+Subject: [PATCH] drm/modes: parse_cmdline: Remove some unnecessary
+ code (v2)
+
+Commit 5b926617cdef41ce0696e09834991194b1759e28 upstream.
+
+fb_get_options() will return fb_mode_option if no video=<connector-name>
+argument is present on the kernel commandline, so there is no need to also
+do this in drm_mode_parse_command_line_for_connector() as our only caller
+uses fb_get_options() to get the mode_option argument.
+
+Changes in v2:
+-Split out the changes dealing with the initialization of the mode struct
+ into a separate patch
+
