V4L/DVB (9091): gspca: Subdriver m5602 (ALi) added. This patch adds support for the ALi m5602 usb bridge and is based on the gspca framework. It contains code for communicating with 5 different sensors: OmniVision OV9650, Pixel Plus PO1030, Samsung S5K83A, S5K4AA and finally Micron MT9M111. Signed-off-by: Erik Andren <erik.andren@gmail.com> Signed-off-by: Jean-Francois Moine <moinejf@free.fr> [mchehab@redhat.com: fix m5602/Makefile] [mchehab@redhat.com: extern debug caused conflicts. Renamed to m5602_debug] Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
