Fixed some compiler warnings. Fixed some compiler warnings.
R0.15 (November 6, 2022)
Changed user provided synchronization functions in order to completely eliminate the platform dependency from FatFs code.
FF_SYNC_t is removed from the configuration options.
Fixed a potential error in f_mount when FF_FS_REENTRANT.
Fixed file lock control FF_FS_LOCK is not mutal excluded when FF_FS_REENTRANT && FF_VOLUMES > 1 is true.
Fixed f_mkfs() creates broken exFAT volume when the size of volume is >= 2^32 sectors.
Fixed string functions cannot write the unicode characters not in BMP when FF_LFN_UNICODE == 2 (UTF-8).
Fixed a compatibility issue in identification of GPT header.
