From c6c20372bbb2f70d2757eed0a8d6860884bae11f Mon Sep 17 00:00:00 2001 From: Dave Reisner Date: Mon, 17 Dec 2012 16:03:01 -0800 Subject: [PATCH] fs/fat: strip "cp" prefix from codepage in display Option parsing code expects an unsigned integer for the codepage option, but prefixes and stores this option with "cp" before passing to load_nls(). This makes the displayed option in /proc an invalid one. Strip the prefix when printing so that the displayed option is valid for reuse.
