Subject: [PATCH 1/2] fs: ntfs: drop unneeded likely() call around IS_ERR()
Date:   Tue, 20 Aug 2019 12:56:11 +0200
Message-Id: <1566298572-12409-1-git-send-email-info@metux.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Enrico Weigelt <info@metux.net>

IS_ERR() already calls unlikely(), so this extra likely() call
around the !IS_ERR() is not needed.
