The recent USB core code performs sanity checks for the given pipe and EP types, and it can be hit by manipulated USB descriptors by syzbot. For making syzbot happier, this patch introduces a local helper for a sanity check in the driver side and calls it at each place before the message handling, so that we can avoid the WARNING splats.

In ALSA firewire-motu driver, some tracepoints are supported to probe vendor-specific data fields for SPH and status/control messages in payload of isochronous packet. At present, the events of tracepoints are unique each of direction, however the pair of events has the same structure and print format. It's possible to unify the pair. This commit unifies the pair. From userspace, direction is specified by filtering for src/dst fields in the structure. Signed-off-by:

This reverts commit e703965a. When creating this patch, I compared the value of src field to the value of first byte of cip_header field (SID) in tracing event. But in this test I used a device which has a quirk to transfer isochronous packet with invalid SID. The original change is valid.

After bus reset, isochronous resource manager releases all of allocated isochronous resources. The nodes to transfer isochronous packet should request reallocation of the resources. However, between the bus-reset and invocation of 'struct fw_driver.update' handler, ALSA PCM application can detect this situation by XRUN because the target device cancelled to transmit packets once bus-reset occurs. Due to the above mechanism, ALSA fireface driver just stops packet streaming in the update handler, thus pcm.prepare handler should request the reallocation. This commit requests the reallocation in pcm.prepare callback when bus generation is changed. Signed-off-by:

Once allocated, isochronous resources are available for packet streaming, even if the streaming is cancelled. For this reason, current implementation handles allocation of the resources and starting packet streaming at the same time. However, this brings complicated procedure to start packet streaming. This commit separates the allocation and starting. The allocation is done in pcm.hw_params callback and available till pcm.hw_free callback. Even if any XRUN occurs, pcm.prepare callback is done to restart packet streaming without releasing/allocating the resources. There are two points to stop packet streaming; in pcm.hw_params and pcm.prepare callbacks. The former point is a case that packet streaming is already started for any MIDI substream then packet streaming is requested with different sampling transfer frequency for any PCM substream. The latter point is cases of any XRUN or packet queueing error. Signed-off-by:

In current implementation, establishment connection corresponds to allocation of isochronous resources. Although this is an ideal implementation of CMP described in IEC 61883-1, it's not enough efficient to recover PCM substream multiplexed in packet streaming. The packet streaming can always restart on the same allocated isochronous resources even if the previous packet streaming corrupted. This commit splits allocation of isochronous resources from establishment of connection so that CMP runs with allocated isochronous resources. Signed-off-by:

In the commit 7f641e26 (ALSA: hda/hdmi - Consider eld_valid when reporting jack event) the eld_valid check was added for the jack event reports. Do the same in sync_eld_via_acomp() function. Apparently, it is required for the NVIDIA proprietary driver (monitor presence reported first, but ELD is available later). Signed-off-by:
