[ Upstream commit 9dea44c91469512d346e638694c22c30a5273992 ]
devm_ioremap_resource() does not currently take 'const' arguments, which results in a warning from the first driver trying to do it anyway:
drivers/gpio/gpio-amd-fch.c: In function 'amd_fch_gpio_probe': drivers/gpio/gpio-amd-fch.c:171:49: error: passing argument 2 of 'devm_ioremap_resource' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers] priv->base = devm_ioremap_resource(&pdev->dev, &amd_fch_gpio_iores); ^~~~~~~~~~~~~~~~~~~
Change the prototype to allow it, as there is no real reason not to.
