Subject: [PATCH] isdn: mISDN: netjet: Replace GFP_ATOMIC with GFP_KERNEL in nj_probe()
Date:   Fri, 27 Jul 2018 10:41:09 +0800
Message-Id: <20180727024109.1702-1-baijiaju1990@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

nj_probe() is never called in atomic context.
It calls kzalloc() with GFP_ATOMIC, which is not necessary.
GFP_ATOMIC can be replaced with GFP_KERNEL.

This is found by a static analysis tool named DCNS written by myself.
