Subject: [PATCH 2/2] mfd/ab8500: Use kstrtoul_from_user
Date: Mon, 20 Jun 2011 16:45:46 +0300	[thread overview]
Message-ID: <BANLkTikKRVP4PW48YtR+mMMNsaxTDxoGtw@mail.gmail.com> (raw)

NAK
You should use kstrtou8_from_user() and drop 0xff check as well.

Do NOT blindly replace strict_strtoul with kstrtoul.
