Commit Message

Disabling the interrupts in the suspend callback leads to a loss of the
wakeup capability in suspend to idle (freeze) mode.

In commit 95dc58a9a02f ("Input: st1232 - rely on I2C core to configure
wakeup interrupt") redundancy was removed by letting the I2C core manage
the wake interrupt handling. On the other hand, the irq enabling/disabling
was generalized to all devices, regardless of their wakeup capabilities.

The interrupt enabling/disabling is carried out by the power subsystem in
the resume/suspend states and therefore there is no need to manage it
in the device driver. Remove the irq handling in the driver-specific
resume/suspend callbacks and rely on the power subsystem.

Fixes: 95dc58a9a02f ("Input: st1232 - rely on I2C core to configure wakeup interrupt")
