Subject: [media] gspca-sonixb: Adjust hstart on sn9c103 + pas202
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0391dc17bd5d7d6b1706d0be6472c4b352b57c05;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[media] gspca-sonixb: Adjust hstart on sn9c103 + pas202

For some unknown reason we need to increase hstart by 1 on when using the
PAS202 on the sn9c103 (versus on the sn9c102), otherwise we get the wrong
colors, due to shifting of the bayer pattern.
