disp: msm: sde: add input handler unregister check before encoder wakeup ...
During PM suspend in dual display usecase, the power off commit to
turn off primary and secondary crtcs is done with only one
drm_atomic_state scheduled on primary crtc_commit thread. At the
same, touch events can happen on secondary panel, which will
run input_event_work and schedule the sde_enc->delayed_off_work
to turn off its enabled resources. There can be race between primary
crtc_commit thread which unregisters input_event, cancels
all the pending works before setting sde_enc->cur_master to NULL
and input_event_work_handler which schedules the delayed_off_work
without checking the input_event_handler state.
This change adds input handler unregister check before triggering
_sde_encoder_rc_early_wakeup.
