[ Upstream commit 889a1b3f35db6ba5ba6a0c23a3a55594570b6a17 ]
If an error occurs after a 'gpiochip_add_data()' call it must be undone by a corresponding 'gpiochip_remove()' as already done in the remove function.
To simplify the code a fix a leak in the error handling path of the probe, use the managed version instead (i.e. 'devm_gpiochip_add_data()')
