Subject: [PATCH] qed: fix kzalloc-simple.cocci warnings
Date: Fri, 21 Apr 2017 08:20:07 +0800	[thread overview]
Message-ID: <20170421002007.GA8379@lkp-sbx04> (raw)
In-Reply-To: <201704210853.tUPLU4Mh%fengguang.wu@intel.com>

drivers/net/ethernet/qlogic/qed/qed_dcbx.c:1267:13-20: WARNING: kzalloc should be used for dcbx_info, instead of kmalloc/memset


 Use kzalloc rather than kmalloc followed by memset with 0

 This considers some simple cases that are common and easy to validate
 Note in particular that there are no ...s in the rule, so all of the
 matched code has to be contiguous
