Subject: pinctrl: imx: Fix the logic checking if not able to find pin reg map
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8d1c6ef67a4530ee5dbd5038d2959a54593013b1;p=linux-beck.git

pinctrl: imx: Fix the logic checking if not able to find pin reg map

Current code sets "pin_reg = &info->pin_regs[i];" in each loop iteration,
so in the case of no-match, pin_reg is not NULL.
