Subject: iomap: mark the iomap argument to iomap_read_page_sync const
X-Git-Tag: v5.15~447^2~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1acd9e9c015b389aa3201a977454efb92e36806c;p=platform%2Fkernel%2Flinux-starfive.git

iomap: mark the iomap argument to iomap_read_page_sync const

iomap_read_page_sync never modifies the passed in iomap, so mark
it const.
