Hi Mukesh,

Is this patch still needed? Can anyone active in the Qualcomm
drivers take a look?

pm_runtime_get_sync() function fails during PM early resume and returning
-EACCES because runtime PM for the device is disabled at the early stage
causing i2c transfer to fail. Make changes to serve transfer with force
resume.

1. Register interrupt with IRQF_EARLY_RESUME and IRQF_NO_SUSPEND flags
    to avoid timeout of transfer when IRQ is not enabled during early stage.
2. Do force resume if pm_runtime_get_sync() is failing after system
    suspend when runtime PM is not enabled.
3. Increment power usage count after forced resume to balance
    it against regular runtime suspend.

Should this be considered a fix?

Thanks,
