Subject: Return CL_IMAGE_FORMAT_NOT_SUPPORTED if image_format is not supported.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fd93252cfa7114759f53ba4e9119ce126181cbc4;p=contrib%2Fbeignet.git

Return CL_IMAGE_FORMAT_NOT_SUPPORTED if image_format is not supported.

And move the function cl_image_byte_per_pixel call before cl_image_get_supported_fmt
to return correct error code when format invalid.
