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)
