Subject: [patch review 2/4] dsbr100: remove usb_dsbr100_open/close calls
Date: Fri, 29 May 2009 00:44:42 +0400	[thread overview]
Message-ID: <1243543482.6713.42.camel@tux.localhost> (raw)

Patch removes usb_dsbr100_open and usb_dsbr100_close calls.
1. No need to start, set frequency, adjust parameters in open call.
2. This patch tackles issue with lock/unlock_kernel() in open call.
3. With this patch feature "Mute on exit?" in gnomeradio works.
