Subject: [PATCH] drm: Fix double free from checking if gamma lut has
|
||
|
|
been updated
|
||
|
|
|
||
|
|
The code falls through to "fail" under all conditions, so there is no
|
||
|
|
need for the drm_property_blob_put if the gamma lut hasn't been changed.
|
||
|
|
Fixes: 9cca26674a2b "drm: Check whether the gamma lut has changed before updating"
