Subject: [PATCH] power: reset: fix __le32 cast in reset code
Date:   Tue, 15 Oct 2019 16:54:14 +0100
Message-Id: <20191015155414.25267-1-ben.dooks@codethink.co.uk>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The writel() takes standard integers, not __le32 so
fix the following sparse warnings by removing the
cpu_to_le32() calls.

drivers/power/reset/at91-reset.c:134:9: warning: cast from restricted __le32
drivers/power/reset/at91-reset.c:143:9: warning: cast from restricted __le32

This has made no code changes, the md5sums pre and post applying
this patch are the same. The at91 should be natively little endian
anyway.
