Subject: sh: mm: re-add lost __ref to ioremap_prot() to fix modpost warning
Date: Mon, 11 Sep 2023 11:38:50 +0200
When __ioremap_caller() was replaced by ioremap_prot(), the __ref
annotation added in commit af1415314a4190b8 ("sh: Flag __ioremap_caller()
__init_refok.") was removed, causing a modpost warning:
WARNING: modpost: vmlinux: section mismatch in reference: ioremap_prot+0x88 (section: .text) -> ioremap_fixed (section: .init.text)
ioremap_prot() calls ioremap_fixed() (which is marked __init), but only
before mem_init_done becomes true, so this is safe. Hence fix this by
re-adding the lost __ref.
