Subject: regmap: Constify static regmap_bus structs
X-Git-Tag: v6.1-rc5~1302^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bd941dfaae3503c6b707d8544696205f759e57a3;p=platform%2Fkernel%2Flinux-starfive.git

regmap: Constify static regmap_bus structs

The only usage of these is to pass their address to __regmap_init() or
__devm_regmap_init(), both which takes pointers to const struct
regmap_bus. Make them const to allow the compiler to put them in
read-only memory.
