[PATCH v2 11/13] drm/msm: only register 'kms' debug file if KMS is used

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is little point in having the empty debugfs file which always
returns -ENODEV. Change this file to be created only if KMS is actually
used.
