Input: tca6416-keypad - fix interrupt enable disbalance
[ Upstream commit cc141c35af873c6796e043adcb820833bd8ef8c5 ]
The driver has been switched to use IRQF_NO_AUTOEN, but in the error
unwinding and remove paths calls to enable_irq() were left in place, which
will lead to an incorrect enable counter value.
Fixes: bcd9730a04a1 ("Input: move to use request_irq by IRQF_NO_AUTOEN flag")
