USB: OTG: msm: Clear in_lpm flag before enabling the IRQ in resume (2ce2c3ac) · Commits · 戴 / test

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. Signed-off-by:
