net: ipa: prevent concurrent replenish
We have seen cases where an endpoint RX completion interrupt arrives while replenishing for the endpoint is underway. This causes another instance of replenishing to begin as part of completing the receive transaction. If this occurs it can lead to transaction corruption. Use a new flag to ensure only one replenish instance for an endpoint executes at a time. Fixes: 84f9bd1 ("soc: qcom: ipa: IPA endpoints") Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
