exfat: replace 'time_ms' with 'time_cs'
Replace time_ms with time_cs in the file directory entry structure and related functions. The unit of create_time_ms/modify_time_ms in File Directory Entry are not 'milli-second', but 'centi-second'. The exfat specification uses the term '10ms', but instead use 'cs' as in msdos_fs.h. Signed-off-by: Tetsuhiro Kohada <kohada.t2@gmail.com> Signed-off-by: Namjae Jeon <namjae.jeon@samsung.com>
