Subject: mmc: sdhci-pltfm: move devm_ioremap_resource() up
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=378382b8d09d43371872103a58e4d4a7ff14b556;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mmc: sdhci-pltfm: move devm_ioremap_resource() up

Call devm_ioremap_resource() right after platform_get_resource().
This saves the error check of platform_get_resource() because
devm_ioremap_resource() checks if the given resource is NULL.
