gpiolib: don't bail out if get_direction() fails in gpiochip_add_data()
Since commit 9d846b1aebbe ("gpiolib: check the return value of
gpio_chip::get_direction()") we check the return value of the
get_direction() callback as per its API contract. Some drivers have been
observed to fail to register now as they may call get_direction() in
gpiochip_add_data() in contexts where it has always silently failed.
Until we audit all drivers, replace the bail-out to a kernel log
warning.
Fixes: 9d846b1aebbe ("gpiolib: check the return value of gpio_chip::get_direction()")
