SubjectRe: [PATCH 2/2] Bluetooth: btmrvl: don't send data to firmware while processing suspend
From
Date
Hi Amitkumar,

> Usually when driver sends data to firmware it receives TX_DONE
> (DN_LD_HOST_INT_STATUS) interrupt from firmware right away.
> It's also observed that some times the fireware could delay
> sending DN_LD_HOST_INT_STATUS interrupt. If driver sends data to
> firmware during suspend processing and the TX_DONE interrupt is
> delayed, it may come back at wrong time when SDIO host driver is
> in the middle of suspending.

> Block any data from stack while suspending. Also skip sending
> data that are already in driver tx_queue.

> Don't purge the skb queue on suspend to avoid intermittent music
> after system resumes from S3.
