[RFC PATCH 1/3] dvbdev: add a dvb_dettach() macro

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

 



The dvb_attach() was unbalanced, as there was no dvb_dettach. Ok,
on current cases, the dettach is done by dvbdev, but that are some
future corner cases where we may need to do this before registering
the frontend.

So, add a dvb_dettach() and use it at dvb_frontend.c.
