[U-Boot] [PATCH v2 1/3] fs/fat: Fix FAT detection to support non-DOS partition tables

Dear Kyle Moffett,

Arghhhh... This causes build warnings:

fat.c: In function 'fat_register_device':
fat.c:66:15: warning: variable 'found_partition' set but not used
[-Wunused-but-set-variable]


I fix this when applying.


Best regards,

Wolfgang Denk
