[media] xc5000: fix xc5000 suspend (91a5307c) · Commits · 戴 / test

After xc5000 stops working, it waits for 5 seconds, waiting for a new usage. Only after that it goes to low power mode. If a suspend event happens before that, a work queue will remain active, with causes suspend to crash. Signed-off-by:
