From 52afbc2f4f1ab78c038bc0d56273ca68021bd3d5 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 8 Aug 2006 09:10:01 -0300 Subject: [PATCH] V4L/DVB (4350): V4L2 conversion: radio_gemtek-pci Driver conversion to V4L2 API. Require some testing, since this obsolete hardware is not common those days.
