It also simplifies the probe to use devm. Regards, Tony Changes since v3: - Use PM runtime to check the last pressed key is not stuck - Simplify probe with devm Changes since v2: - Drop bogus level change, that already comes from device tree - Scan keyboard in two phases and simplify using a bitmask - Use mod_delayed_work and cancel_delayed_work_sync for the quirk Tony Lindgren (4): Input: omap4-keypad - disable unused long interrupts Input: omap4-keypad - scan keys in two phases and simplify with bitmask Input: omap4-keypad - use PM runtime to check keys for errata Input: omap4-keypad - simplify probe with devm drivers/input/keyboard/omap4-keypad.c | 255 +++++++++++++++++--------- 1 file changed, 170 insertions(+), 85 deletions(-)
