Subject: [PATCH] net: wireless: ath6kl: Replace GFP_ATOMIC with GFP_KERNEL in ath6kl_bmi_init()
Date: Fri, 27 Jul 2018 16:43:18 +0800 [thread overview]
Message-ID: <20180727084318.3345-1-baijiaju1990@gmail.com> (raw)
ath6kl_bmi_init() 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.
