The quilt patch titled
     Subject: sh: mm: re-add lost __ref to ioremap_prot() to fix modpost warning
has been removed from the -mm tree.  Its filename was
     sh-mm-re-add-lost-__ref-to-ioremap_prot-to-fix-modpost-warning.patch

This patch was dropped because it was merged into the mm-hotfixes-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

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.
