From: Mauro Carvalho Chehab Date: Tue, 8 Aug 2006 12:10:03 +0000 (-0300) Subject: V4L/DVB (4356): V4L2 conversion: radio-terratec X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=55ac7b690f086112ab8ac35764189269cdfae768;p=linux-beck.git V4L/DVB (4356): V4L2 conversion: radio-terratec Driver conversion to V4L2 API. Require some testing, since this obsolete hardware is not common those days.
