From 1bf00d7a6dbff0a29eff4f8c022653b2bc9f5b97 Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Tue, 23 Sep 2014 21:05:40 +0200 Subject: [PATCH] pinctrl: samsung: Constify samsung_pin_ctrl struct In order to separate initialization constants from runtime data, this patch modifies the driver to store only constant data in samsung_pin_ctrl struct and copy data required at runtime to samsung_pinctrl_drv_data struct. This makes it possible to mark all existing instances of samsung_pin_ctrl struct as const and __initconst.
