[PATCH 3/5] Input: tca6416-keypad - fix interrupt enable disbalance

From: Dmitry Torokhov
Date: Mon Jul 24 2023 - 01:30:51 EST


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")
