2016-04-15crypto: qat - adf_dev_stop should not be called in atomic contextTadeusz Struk3-3/+64
VFs call adf_dev_stop() from a PF to VF interrupt bottom half. This causes an oops "scheduling while atomic", because it tries to acquire a mutex to un-register crypto algorithms. This patch fixes the issue by calling adf_dev_stop() asynchronously. Changes in v2: - change kthread to a work queue.
