Subject: [PATCH V3] Bluetooth: bt3c_cs: Fix obsolete function
Date:   Sun, 26 Aug 2018 22:55:00 -0400
Message-Id: <1535338500-7682-1-git-send-email-dingxiang@cmss.chinamobile.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

simple_strtol and simple_strtoul are obsolete, both place
use kstrtouint instead.

V2: fix error tmp += tn
V3: fix compile error
