From acda0e71857c8ec4e5348d08b53a52d35b92e6aa Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 8 Aug 2006 09:10:02 -0300 Subject: [PATCH] V4L/DVB (4355): V4L2 conversion: radio-sf16fmr2 Driver conversion to V4L2 API. Require some testing, since this obsolete hardware is not common those days.
