Subject: crypto: dcp - Use devm_ioremap_resource()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=05a27928f37b31ea8b844e3b0c623d7f46451145;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

crypto: dcp - Use devm_ioremap_resource()

Using devm_ioremap_resource() can make the code simpler and smaller.

When devm_ioremap_resource() is used there is no need to explicitely check the
error returned by platform_get_resource().
