The ioreadX() helpers accept now pointer to const memory so declaration
of read function needs updating.
This fixes build errors like:
drivers/sh/clk/cpg.c: In function ‘sh_clk_mstp_enable’:
drivers/sh/clk/cpg.c:49:9: error: assignment from incompatible pointer type [-Werror=incompatible-pointer-types]
read = ioread8;

Dear Andrew,
This was part of my v3 patchset commit 9ab7fb303cc1 ("iomap: Constify
ioreadX() iomem argument (as in generic implementation)") but I think it
was skipped when applying to your tree.
Maybe because it depends on commit 58c4d8659186 ("sh: clkfwk: remove
r8/r16/r32") which landed later? Anyway it should go through your tree,
I think.

Is that a reverted patch, by any chance? The patch does not apply for me and looking at
the sources, the qualifier is already "const" [1].

The patch is for Andrew Morton's tree which contain two commits:
1. sh: clkfwk: remove r8/r16/r32
2. iomap: constify ioreadX() iomem argument (as in generic implementation)
This patch here was actually part of #2 because of being based on
linux-next. However it disappeared when applying to Andrew's tree
because patch #1 came later.
Best regards,
Krzysztof

Okay. I'll try to look at the other two patches later.
