When queuing an OUTPUT buffer for decoder, s5p_jpeg_parse_hdr()
function parses the input jpeg file and takes the width and height
parameters from its header. These new width/height values will be used
for the calculation of stride. HX_JPEG Hardware needs the width and
height values aligned on a 16 bits boundary. This width/height alignment
is handled in the s5p_jpeg_s_fmt_vid_cap() function during the S_FMT
ioctl call.
But if user space calls the QBUF of OUTPUT buffer after the S_FMT of
CAPTURE buffer, these aligned values will be replaced by the values in
jpeg header. If the width/height values of jpeg are not aligned, the
decoder output will be corrupted. So in this patch we call
jpeg_bound_align_image() to align the width/height values of Capture
buffer in s5p_jpeg_buf_queue().
