Subject: mm/mem-hotplug: replace simple_strtoull() with kstrtoull()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b69deb2b7e13f04da5c0684c7ce19e788736ab0d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mm/mem-hotplug: replace simple_strtoull() with kstrtoull()

Use the newer and more pleasant kstrtoull() to replace
simple_strtoull(), because simple_strtoull() is marked for obsoletion.
