Subject: pinctrl: bcm: Constify static pinctrl_ops
X-Git-Tag: accepted/tizen/unified/20230118.172025~6934^2~12
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d9779093676bd8743ba2e1cd971f4eabb15c060d;p=platform%2Fkernel%2Flinux-rpi.git

pinctrl: bcm: Constify static pinctrl_ops

These are only assigned, either directly or via the bcm63xx_pinctrl_soc
struct, to the pctlops field in the pinctrl_desc struct and never
modified, so make them const to allow the compiler to put them in
read-only memory.
