Subject[PATCH 3.12 055/181] mfd: sm501: dbg_regs attribute must be read-only
Date
From: Guenter Roeck <linux@roeck-us.net>

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

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

commit 8a8320c2e78d1b619a8fa8eb5ae946b8691de604 upstream.

Fix:

sm501 sm501: SM501 At b3e00000: Version 050100a0, 8 Mb, IRQ 100
Attribute dbg_regs: write permission without 'store'
------------[ cut here ]------------
WARNING: at drivers/base/core.c:620

dbg_regs does not have a write function and must therefore be marked
as read-only.
