[PATCH] fat_lock is used as a mutex, convert it to using the new mutex primitive

static inline void lock_fat(struct msdos_sb_info *sbi)

{

	down(&sbi->fat_lock);

	mutex_lock(&sbi->fat_lock);

}

static inline void unlock_fat(struct msdos_sb_info *sbi)

{

	up(&sbi->fat_lock);

	mutex_unlock(&sbi->fat_lock);

}

void fat_ent_access_init(struct super_block *sb)

{

	struct msdos_sb_info *sbi = MSDOS_SB(sb);

	init_MUTEX(&sbi->fat_lock);

	mutex_init(&sbi->fat_lock);

	switch (sbi->fat_bits) {

	case 32:
