Looks like the adjusted syntax wasn't fully build tested. This fixes
failures with powerpc builds:
drivers/mmc/host/mxcmmc.c: In function ‘mxcmci_swap_buffers’:
drivers/mmc/host/mxcmmc.c:296:51: error: expected ‘)’ before ‘;’ token
void *buf = kmap_atomic(sg_page(sg) + sg->offset;
^
drivers/mmc/host/mxcmmc.c:299:1: error: expected ‘,’ or ‘;’ before ‘}’ token
}
^
Fixes: b189e7589f6d3 ("mmc: mxcmmc: handle highmem pages")

I just checked again, and while I see this in linux-next, I would
expect this to be in 4.18, since this fixes a 4.18-introduced build
failure for some PPC configurations. Can this please be included in
4.18?
Thanks!

Yes it will, I was just about to create a PR for it.
However, I have deliberately slowed down the pace of sending fixes to
Linus, because of trying to achieve a somewhat better test coverage.
If you want to test the latest 4.18 rcs with pending fixes, we have
the pending-fixes branch in Stephen's next tree.

Kind regards
