From f3b4b7c48e5998af8c009821c7dbb2137db33b35 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 1 Sep 2016 20:42:19 +0200 Subject: pinctrl: ns2: 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.
