filetype: Improve FAT detection
We may have some disk with MBR as a first sector. In this case, the current FAT check returns an error. However, the FAT sector exist and the MBR can tell us where it is. This patch add to file_name_detect_type function the ability to find the FAT boot sector on the first sector of the first partition in case it is not on sector 0. It also introduce is_fat_or_mbr to check if a buffer is a FAT boot or MBR sector Signed-off-by: Franck Jullien <franck.jullien@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
