V4L/DVB (8311): sms1xxx: support device-specific firmware filenames on stellar usb1 sticks
Add the capability to define device-specific firmware filenames for the SMS1010, with a mechanism to fall back to the generic firmware if the device-specific firmware is not present. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
