Subject: drm/rockchip: vop: fixup linebuffer mode calc error
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=106359177a57c7ea4a0c31e9cd24e6313b355ed7;p=linux.git

drm/rockchip: vop: fixup linebuffer mode calc error

linebuffer mode should be LB_YUV_3840X5 when width is bigger than 1280
in yuv mode.

Separate yuv and rgb case makes the scl_vop_cal_lb_mode() logic clearer.
