From e84fef6b4a9d36fea53354633c590a7800d9fd83 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 8 Aug 2006 09:10:05 -0300 Subject: [PATCH] V4L/DVB (4364): V4L2 conversion: radio-maxiradio Driver conversion to V4L2 API. Require some testing, since this obsolete hardware is not common those days.
