This patch breaks the build:

drivers/staging/exfat/exfat_super.c: In function ‘ffsMountVol’:
drivers/staging/exfat/exfat_super.c:387:9: error: ‘FFS_FORMATERR’ undeclared (first use in this function)
  387 |   ret = FFS_FORMATERR;
      |         ^~~~~~~~~~~~~


Did you test-build this thing?

thanks,

greg k-h
