[PATCH 125/205] USB: OTG: msm: Clear in_lpm flag before enabling the IRQ in resume

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Pavankumar Kondeti <pkondeti@xxxxxxxxxxxxxx>

The current code is clearing in_lpm flag after enabling the IRQ.
If IRQ comes immediately before in_lpm flag is set, it thinks that
hardware is in low power mode and disables the IRQ.  Fix this by
clearing in_lpm flag before enabling the IRQ.
