> Subject: [PATCH v3] crypto: aspeed: fix type warnings
>
> 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: use readb to avoid dereferencing the memory.
>
> Signed-off-by: Neal Liu <neal_liu@xxxxxxxxxxxxxx>
> ---
> Change since v2: remove unnecessary cast.
> Change since v1: keep iomem marker to remain its purpose.
