From 5fe2501fbf8d21d57fef2eb0a54d50f5a0c6f4c4 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 1 Sep 2016 20:42:21 +0200 Subject: [PATCH] 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.
