When using mcp23s08 module with gpio-keys, often (50% of boots) it fails to get irq numbers with message: "gpio-keys keys: Unable to get irq number for GPIO 0, error -6". Seems that irqs must be setup before devm_gpiochip_add_data(). Cc: stable@vger.kernel.org Signed-off-by:

pinctrl/devinfo.h is using forward declaration from pinctrl/consumer.h for configurations with CONFIG_PINCTRL defined, however nothing declares it in the opposite case. Fix this by adding a forward declaration. Signed-off-by:

Without such a range, gpiolib fails with -EPROBE_DEFER, pending the addition of the range. So, without a range, gpiolib will keep deferring indefinitely.

There is no matching call to pinctrl_unregister, so switch to the managed devm_pinctrl_register to clean up properly when done. Cc: stable@vger.kernel.org Fixes: 9e80f906 ("pinctrl: Add SX150X GPIO Extender Pinctrl Driver") Signed-off-by:

commit d6ed9355 ("pinctrl: mediatek: add pinctrl driver for MT7622 SoC") leads to the following static checker warning: drivers/pinctrl/mediatek/pinctrl-mt7622.c:1419 mtk_gpio_get() error: uninitialized symbol 'value'. 1412 static int mtk_gpio_get(struct gpio_chip *chip, unsigned int gpio) 1413 { 1414 struct mtk_pinctrl *hw = dev_get_drvdata(chip->parent); 1415 int value; 1416 1417 mtk_hw_get_value(hw, gpio, PINCTRL_PIN_REG_DI, &value); ^^^^^^^^^^^^^^^^ 1418 1419 return !!value; 1420 } The appropriate error handling must be added to avoid the potential error caused by uninitialized value being returned.

Stefan Agner authored
For some SoCs the struct imx_pinctrl_soc_info is passed through of_device_id.data which is const. Most variables are already const or otherwise not written. However, some fields are modified at runtime. Move those fields to the dynamically allocated struct imx_pinctrl.

Pin function can not be match correctly when SUNXI_PIN describe with mutiple variant and same function. such as: on pinctrl-sun4i-a10.c SUNXI_PIN(SUNXI_PINCTRL_PIN(B, 2), SUNXI_FUNCTION(0x0, "gpio_in"), SUNXI_FUNCTION(0x1, "gpio_out"), SUNXI_FUNCTION_VARIANT(0x2, "pwm", /* PWM0 */ PINCTRL_SUN4I_A10 | PINCTRL_SUN7I_A20), SUNXI_FUNCTION_VARIANT(0x3, "pwm", /* PWM0 */ PINCTRL_SUN8I_R40)), it would always match to the first variant function (PINCTRL_SUN4I_A10, PINCTRL_SUN7I_A20) so we should add variant compare on it.

This driver creates a const structure that it stores in the data field of an of_device_id array. Adding const to the declaration of the location that receives the const value from the data field ensures that the compiler will continue to check that the value is not modified. Furthermore, the const-discarding cast on the extraction from the data field is no longer needed. Done using Coccinelle. Signed-off-by:
