pinctrl: bcm281xx: constify pinctrl_ops and pinmux_ops structures
Check for pinctrl_ops and pinmux_ops structures that are only stored in the
pctlops field and the pmxops field, respectively, of a pinctrl_desc
structure. These fields are declared const, so pinctrl_ops and pinmux_ops
structures that have this property can be declared as const also.
The semantic patch that makes this change in the pinctrl_ops is as
follows. The pinmux_ops case is similar. (http://coccinelle.lip6.fr/)
