Rahul Rameshbabu 4919297c3f HID: multitouch: Correct devm device reference for hidinput input_dev name 
BugLink: https://bugs.launchpad.net/bugs/2040284

[ Upstream commit 4794394635293a3e74591351fff469cea7ad15a2 ]

Reference the HID device rather than the input device for the devm
allocation of the input_dev name. Referencing the input_dev would lead to a
use-after-free when the input_dev was unregistered and subsequently fires a
uevent that depends on the name. At the point of firing the uevent, the
name would be freed by devres management.

Use devm_kasprintf to simplify the logic for allocating memory and
formatting the input_dev name string.
