Input: synaptics-rmi4 - fail probing if memory allocation for "phys" fails
[ Upstream commit bc4996184d
]
While input core can work with input->phys set to NULL userspace might
depend on it, so better fail probing if allocation fails. The system must
be in a pretty bad shape for it to happen anyway.
