2018-01-22pinctrl: Forward declare struct deviceLadislav Michl
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: Ladislav Michl <ladis@linux-mips.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

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

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.
