gspca - gl860: updates to prepare the new driver for MI2020 sensor
From: Olivier Lorin <o.lo...@laposte.net>
- General changes for all drivers because of new MI2020 sensor driver :
- add the light source control
- control value changes only applied after an end of image
- replace msleep with duration less than 5 ms by a busy loop
- Fix for an irrelevant OV9655 image resolution identifier name
Priority: normal
Signed-off-by: Olivier Lorin <o.lo...@laposte.net>
