+Subject: [PATCH] drm/modes: parse_cmdline: Explicitly memset the
+ passed in drm_cmdline_mode struct
+
+Commit d1fe276b5115f0d581c3cfe6154633b3547e8aab upstream.
+
+Instead of only setting mode->specified on false on an early exit and
+leaving e.g. mode->bpp_specified and mode->refresh_specified as is,
+lets be consistent and just zero out the entire passed in struct at
+the top of drm_mode_parse_command_line_for_connector()
+
+Changes in v3:
+-Drop "mode->specified = false;" line instead of the "return false;" (oops)
+ This crasher was reported-by: kernel test robot <lkp@intel.com>
+
