Subject: mm/early_ioremap: add explicit #include of asm/early_ioremap.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4f1af60bcc2fc6caa7fa3036238b5994708e9a84;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mm/early_ioremap: add explicit #include of asm/early_ioremap.h

Commit 6b0f68e32ea8 ("mm: add utility for early copy from unmapped ram")
introduces a function copy_from_early_mem() into mm/early_ioremap.c
which itself calls early_memremap()/early_memunmap().  However, since
early_memunmap() has not been declared yet at this point in the .c file,
nor by any explicitly included header files, we are depending on a
transitive include of asm/early_ioremap.h to declare it, which is
fragile.

So instead, include this header explicitly.
