Subject: [PATCH] fs: FAT: Cleanup string initializations (char[] instead of char *)

Initializations like 'char *foo = "bar"' will create two variables: a static
string and a pointer (foo) to that static string. Instead 'char foo[] = "bar"'
will declare a single variable and will end up in shorter
assembly (according to Jeff Garzik on the KernelJanitor's TODO list).
