From 17c7cbb0e7b7a877f1ce2063d7f869801b24cd6a Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 12 Mar 2015 11:09:15 +0100 Subject: [PATCH] pinctrl: sh-pfc: Use reg_width instead of reg as sentinel All other loops over sh_pfc_soc_info.data_regs[] use pinmux_data_reg.regwidth as the sentinel, which is safer as zero is never a valid regwidth value (reg could be zero if we start using it to store an offset).
