Commit 3dac1918a491 ("pinctrl: imx: detect uninitialized pins") needs
the values in struct imx_pin_reg to be -1. This has been done in a
rather unorthodox way by setting the memory to 0xff using memset...
Use a proper for loop to initialize the whole array with -1.Signed-off-by: Stefan Agner <[email protected]> --- drivers/pinctrl/freescale/pinctrl-imx.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/drivers/pinctrl/freescale/pinctrl-imx.c b/drivers/pinctrl/freescale/pinctrl-imx.c index 52f2b94..95041b6 100644 --- a/drivers/pinctrl/freescale/pinctrl-imx.c +++ b/drivers/pinctrl/freescale/pinctrl-imx.c @@ -645,7 +645,7 @@ int imx_pinctrl_probe(struct platform_device *pdev, { struct imx_pinctrl *ipctl; struct resource *res; - int ret; + int ret, i; if (!info || !info->pins || !info->npins) { dev_err(&pdev->dev, "wrong pinctrl info\n"); @@ -662,7 +662,11 @@ int imx_pinctrl_probe(struct platform_device *pdev, info->npins, GFP_KERNEL); if (!info->pin_regs) return -ENOMEM; - memset(info->pin_regs, 0xff, sizeof(*info->pin_regs) * info->npins); + + for (i = 0; i < info->npins; i++) { + info->pin_regs[i].mux_reg = -1; + info->pin_regs[i].conf_reg = -1; + } res = platform_get_resource(pdev, IORESOURCE_MEM, 0); ipctl->base = devm_ioremap_resource(&pdev->dev, res); -- 2.2.2 -- To unsubscribe from this list: send the line "unsubscribe linux-gpio" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
