Subject: exynos: vdec: report width/height as stride/slice-height for BUFFER_COPY
X-Git-Url: https://git.stricted.de/?p=GitHub%2FLineageOS%2Fandroid_hardware_samsung_slsi_exynos5.git;a=commitdiff_plain;h=4baab539d5854f3270e6eb5a3d12e5be0fd8bdef

exynos: vdec: report width/height as stride/slice-height for BUFFER_COPY

This is a workaround for bytebuffer mode, as decoder actually uses width
and height as stride and slice height for the output buffer.  Changing
only at getParam as the internal value may be used elsewhere.
