Subject: gpio/pca953x bugfix: mark as can_sleep
From: Arnaud Patard <arnaud.patard@xxxxxxxxxxx>
The pca953x driver is an I2C driver so gpio_chip->can_sleep should be set.
This lets upper layers know they should use the gpio_*_cansleep() calls to
access values, and may not access them from nonsleeping contexts.
