From 5f5e26b1e6c23f23e9b116a4439437e752e56eb7 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 14 Aug 2009 10:40:26 -0300 Subject: [PATCH] V4L/DVB (12621): gspca_mr97310a: Move detection of CIF sensor type to probe() function gspca_mr97310a: Move detection of CIF sensor type to probe() function, so that the right controls are set to disabled from the start, rather then having them disappear all of a sudden when the stream is started.
