From: Hans de Goede Date: Wed, 3 Sep 2008 20:12:15 +0000 (-0300) Subject: V4L/DVB (8816): gspca: Set disabled ctrls and fix a register pb with ovxxxx in sonixb. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e2ad2a54ad1e0f8d7c9e49c38b552a630e015af3;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git V4L/DVB (8816): gspca: Set disabled ctrls and fix a register pb with ovxxxx in sonixb. - set some controls as disabled instead of copying the device descr. - in the ov6650 / 7650 exposure code clamp reg 11 before (instead of after) using it to calculate reg 10. - disable brightness (instead of ignoring it) for the TAS5110.
