V4L/DVB (13179): gspca_ov519: cache sensor regs to avoid unnecessary slow i2c reads / writes Cache sensor regs to avoid unnecessary slow i2c reads / writes, this speeds up sd_start a bit with most bridges and a lot (from 5 seconds down to 0.3 seconds) with W996xCF cams, as this avoids very slow bit bang IO over USB i2c reads.
