Subject: [PATCH] Input: matrix_keypad - use request_any_context_irq()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

When trying to use the matrix-keypad driver with GPIO drivers that
require nested irq handlers (e.g. I2C GPIO adapters like PCA9554),
request_irq() fails because the GPIO driver requires a threaded
interrupt handler.

Use request_any_context_irq() to be able to use any GPIO driver as
keypad driver.
