Subject: mfd: sm501: dbg_regs attribute must be read-only
X-Git-Tag: next-20130912~31^2~3
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=257f45e91bcd64e17cf344a53b095239c42b8035;p=karo-tx-linux.git

mfd: sm501: dbg_regs attribute must be read-only

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.
