[PATCH v4 04/17] media: blackfin: bfin_capture: set vb2 buffer field

From: Lad Prabhakar
Date: Sun Mar 08 2015 - 10:45:41 EST


From: "Lad, Prabhakar" <prabhakar.csengg@xxxxxxxxx>

set the vb2 buffer field in buf_prepare() callback,
alongside drop local variable buf as we already have
a pointer to vb2 buffer.
