[PATCH 1/2] drm/vmwgfx: make vmw_kms_helper_dirty return an initialized value

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

 



In vmw_kms_helper_dirty(), local variable ret is never initialized
before begin used in a return statement when vmw_fifo_reserve() fails.
Instead of returning an uninitialized value, return -ENOMEM here and
remove the useless variable.
