Subject: [PATCH net-next, 2/4] hv_netvsc: Simplify num_chn checking in rndis_filter_device_add()
Date: Fri,  1 Sep 2017 14:30:05 -0700	[thread overview]
Message-ID: <20170901213007.10325-3-haiyangz@exchange.microsoft.com> (raw)
In-Reply-To: <20170901213007.10325-1-haiyangz@exchange.microsoft.com>

From: Haiyang Zhang <haiyangz@microsoft.com>

The minus one and assignment to a local variable is not necessary.
This patch simplifies it.
