Subject: media: mtk-vcodec: vdec: fix incorrect pointer dereference
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=dda8415e17c99ad3d6ac56d8aa722198f816fc74;p=android-x86%2Fkernel.git

media: mtk-vcodec: vdec: fix incorrect pointer dereference

mtk_q_data::fmt is actually a pointer and must be dereferenced as such.
This went under the radar because mtk_v4l2_debug() evaluates to nothing
unless DEBUG is defined.
