pinctrl: pinctrl-imx: don't use invalid value of conf_reg
The right check for conf_reg to be invalid it testing against -1 not 0 as is done in the rest of the driver. This fixes an oops that can be triggered by: cat /sys/kernel/debug/pinctrl/43fac000.iomuxc/* Fixes: ae75ff814538 ("pinctrl: pinctrl-imx: add imx pinctrl core driver") Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
