Subject: conditionally define U32_MAX
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=77719536dc00f8fd8f5abe6dadbde5331c37f996;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

conditionally define U32_MAX

The symbol U32_MAX is defined in several spots.  Change these
definitions to be conditional.  This is in preparation for the next
patch, which centralizes the definition in <linux/kernel.h>.
