media: s5p-jpeg: Check for fmt_ver_flag when doing fmt enumeration
Previously when doing format enumeration, it was returning all formats supported by driver, even if they're not supported by hw. Add missing check for fmt_ver_flag, so it'll be fixed and only those supported by hw will be returned. Similar thing is already done in s5p_jpeg_find_format. It was found by using v4l2-compliance tool and checking result of VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS test and using v4l2-ctl to get list of all supported formats. Tested on s5pv210-galaxys (Samsung i9000 phone). Fixes: bb677f3ac434 ("[media] Exynos4 JPEG codec v4l2 driver") Signed-off-by: Pawe?
