Hans Verkuil 86dfb47094 pinctrl-bcm2835.c: fix race condition when setting gpio dir ... [ Upstream commit b7badd752d ] In the past setting the pin direction called pinctrl_gpio_direction() which uses a mutex to serialize this. That was changed to set the direction directly in the pin controller driver, but that lost the serialization mechanism. Since the direction of multiple pins are in the same register you can have a race condition, something that was in fact observed with the cec-gpio driver. Add a new spinlock to serialize writing to the FSEL registers.
