Subject: [PATCH 1337/1350] Input: matrix_keypad - avoid repeatedly converting
|
|
GPIO to IRQ
|
|
|
|
commit a96fb711c6be76bcfbcf594a865002fa7c0eb525 upstream.
|
|
|
|
There is no need to do conversion from GPIOs to interrupt numbers.
|
|
Convert row GPIOs to interrupt numbers once in probe() and use
|
|
this information when the driver needs to enable or disable given
|
|
interrupt line.
