Subject: crypto: atmel-aes - Use devm_platform_get_and_ioremap_resource()
X-Git-Tag: v6.6.17~4031^2~111
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3aaafe054b7140418c9355512bc1a7a4980943c3;p=platform%2Fkernel%2Flinux-rpi.git

crypto: atmel-aes - Use devm_platform_get_and_ioremap_resource()

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.
