Fabian Vogt 4ba8b5ca22 Input: nspire-keypad - enable interrupts only when opened 
[ Upstream commit 69d5ff3e9e51e23d5d81bf48480aa5671be67a71 ]

The driver registers an interrupt handler in _probe, but didn't configure
them until later when the _open function is called. In between, the keypad
can fire an IRQ due to touchpad activity, which the handler ignores. This
causes the kernel to disable the interrupt, blocking the keypad from
working.

Fix this by disabling interrupts before registering the handler.
Additionally, disable them in _close, so that they're only enabled while
open.

Fixes: fc4f31461892 ("Input: add TI-Nspire keypad support")
