These structures are only used to copy into other structures, so declare
them as const.The semantic patch that makes this change is as follows:

This driver has .can_sleep flag set.
So the pisosr_gpio_get() can be called from contexts that can sleep.
Thus use the cansleep() variant in pisosr_gpio_refresh().Signed-off-by: Axel Lin

Add generic parallel-in/serial-out shift register GPIO driver.
This includes SPI compatible devices like SN74165 serial-out shift
registers and the SN65HVS88x series of industrial serializers that can
be read over the SPI bus and used for GPI (General Purpose Input).Signed-off-by: Andrew F. Davis
