Hi,

This series updates omap4-keypad to disable unused long interrupts, and
implements the missing parts for the lost key-up interrupt quirk as
described in the silicon errata pdf. 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
