[PATCH] strtok --> strsep in filesystem drivers (part 2)

[René Scharfe]

Hi,

this part finishes off the rest of the strtok() calls in filesystem
drivers. In some of them (FAT, VFAT, NTFS) we need to declare our own
char pointer to preserve the value of the original pointer. Apart from
that it's just a plain strtok() replacement. Please, apply.

René
