Subject: [PATCH-next] crypto: aspeed: fix type warnings
Date:   Thu, 2 Feb 2023 10:56:00 +0800
Message-ID: <20230202025600.2598548-1-neal_liu@aspeedtech.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 7BIT
Content-Type:   text/plain; charset=US-ASCII
Precedence: bulk

This patch fixes following warnings:

1. sparse: incorrect type in assignment (different base types)
Fix: change to __le32 type.
2. sparse: cast removes address space '__iomem' of expression
Fix: change to force cast.
