Subject[PATCH 6/7] fs/fat: Fix all other checkpatch issues in dir.c
Date
This does the following:

1: Import linux/uaccess.h instead of asm.uaccess.h
2: Stop any lines going over 80 characters
3: Stopped setting any variables in if statements
4: Stopped splitting quoted strings
5: Removed unneeded parentheses
