Subject[PATCH 2/2 v2] Unify rest of FAT messages.
Date
Here is how it looks like after patch.

[50334.635174] FAT-fs (loop0): utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!
[50334.635178]
[50334.635606] FAT-fs (loop0): Invalid FSINFO signature: 0x00000000, 0x00000000 (sector = 1)
[50334.635666] FAT-fs (loop0): Mounted. Opts: iocharset=utf8
[50342.129047] FAT-fs (loop0): error, invalid access to FAT (entry 0x9e90a346)
[50342.129306] FAT-fs (loop0): error, invalid access to FAT (entry 0xa35ced48)
v2 - more protoype to other patch
