Subject: [PATCH 3/6] ply-device-manager: Move verify_drm_device() higher up in
|
||
|
|
the file
|
||
|
|
|
||
|
|
Move verify_drm_device() higher up in ply-device-manager.c, this is
|
||
|
|
a preparation patch for the next patch in this series.
|
||
|
|
|
||
|
|
This is a pure move without any changes to the moved block.
