Please check the following build error:

fs/exfat/dir.c: In function ‘exfat_validate_vendor_alloc’:
fs/exfat/dir.c:688:24: error: implicit declaration of function
‘EXFAT_CLU_TO_B’; did you mean ‘EXFAT_ACLTAB’?
[-Werror=implicit-function-declaration]
  688 |         u64 max_size =
EXFAT_CLU_TO_B((u64)EXFAT_DATA_CLUSTER_COUNT(sbi), sbi);

Thanks.
