[PATCH v2 4/5] media: v4l2: move v4l_fill_fmtdesc to common v4l2_fill_fmtdesc function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The function v4l_fill_fmtdesc is a function that fills v4l2_fmtdesc with
its description data and compressed flag that is matching the
pixelformat. Since more v4l2 users other than v4l_enum_fmt can benefit
from it we move the function to the v4l2-common code and rename it to
v4l2_fill_fmtdesc.
