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().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
