Subject: [PATCH 3.12 67/94] mtd: devices: elm: fix elm_context_save() and elm_context_restore() functions

From: Ted Juan <ted.juan@...il.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 6938ad40cb97a52d88a763008935340729a4acc7 upstream.

These two function's switch case lack the 'break' that make them always
return error.
