Subject: [PATCH v4 4/4] Staging: rtl8723bs: Use !x instead of NULL comparison
Date:   Wed, 24 Jan 2018 05:43:02 +0530
Message-Id: <99315a25b008ec1e53bd98dd3230143f9d5e9b04.1516751432.git.shreeya.patel23498@gmail.com>
In-Reply-To: <cover.1516751432.git.shreeya.patel23498@gmail.com>
References: <cover.1516751432.git.shreeya.patel23498@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

If "x" is compared to NULL, use "!x" instead of it, so as
to follow the kernel coding style.
