[PATCH 07/17] staging: tidspbridge: remove rmm_init() and rmm_exit()

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

 



The rmm module has a rmm_init() and a rmm_exit() whose only purpose is
to keep a reference counting which is not used at all.

This patch removes these functions and the reference count variable.

There is no functional changes.
