2015-11-30pinctrl: at91-pio4: use %pr format string for resourceArnd Bergmann
resource_size_t may be defined as 32 or 64 bit depending on configuration, so it cannot be printed using the normal format strings, as gcc correctly warns: pinctrl-at91-pio4.c: In function 'atmel_pinctrl_probe': pinctrl-at91-pio4.c:1003:41: warning: format '%u' expects argument of type 'unsigned int', but argument 5 has type 'resource_size_t {aka long long unsigned int}' [-Wformat=] dev_dbg(dev, "bank %i: hwirq=%u\n", i, res->start); This changes the format string to use the special "%pr" format string that prints a resource, and changes the arguments so we the resource structure directly.

2015-11-19gpio: change member .dev to .parentLinus Walleij
The name .dev in a struct is normally reserved for a struct device that is let us say a superclass to the thing described by the struct. struct gpio_chip stands out by confusingly using a struct device *dev to point to the parent device (such as a platform_device) that represents the hardware. As we want to give gpio_chip:s real devices, this is not working. We need to rename this member to parent. This was done by two coccinelle scripts, I guess it is possible to combine them into one, but I don't know such stuff. They look like this: @@ struct gpio_chip *var; @@ -var->dev +var->parent and: @@ struct gpio_chip var; @@ -var.dev +var.parent and: @@ struct bgpio_chip *var; @@ -var->gc.dev +var->gc.parent Plus a few instances of bgpio that I couldn't figure out how to teach Coccinelle to rewrite. This patch hits all over the place, but I *strongly* prefer this solution to any piecemal approaches that just exercise patch mechanics all over the place. It mainly hits drivers/gpio and drivers/pinctrl which is my own backyard anyway.

Irq argument as been removed from irq flow handlers so use the irq descriptor to retrieve data we need. Signed-off-by: Ludovic Desroches <ludovic.desroches@atmel.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Use irq_set_handler_locked() as it avoids a redundant lookup of the irq descriptor. Signed-off-by: Ludovic Desroches <ludovic.desroches@atmel.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
