There's also one core fix for an issue when unbinding a card which for some reason had managed to not manifest until recently.

To use it as more open driver, rsrc-card will be renamed to simple-scu-card. In order to easy patch review, as 2nd step, this patch adds new compatible "simple-scu-audio-card"; rcar-card used specific property, not "simple-audio-card", but it should be now. Actually, rsrc-card is upstreamed driver, but noone is using it on upstream. The user is only local, and it is only me. Thus, there is no compatible break by this patch. This patch uses "simple-audio-card" prefix. And it removes rcar-card specifix compatible too.

2016-08-22ALSA: usb: fine-tune Tenor error compensation valueDaniel Mack
Users of devices affected by the Tenor feedback data error report buffer underruns, even with the +/- 0x1.0000 quirk applied. Compensating the error with 0xf000 instead seems to reliably fix that issue.

The quirk seems to be necessary not only for TEAC UD-H01 devices, but to more that are based on the Tenor 8802TL chipset. Devices built by T+A are affected too, and they apparently all use the same USB PID:PID. Extend the quirky handling for that device as well, and rename the quirks flag.

2016-08-22ALSA: seq: add an alternative way to handle ioctl requestsTakashi Sakamoto
ALSA sequencer is designed with two types of clients; application and kernel. Operations for each ioctl command should handle data in both of user space and kernel space, while current implementation just allows them to handle data in user space. Data in kernel space is handled with change of address limit of running tasks. This commit adds a new table to map ioctl commands to corresponding functions. The functions get data in kernel space. Helper functions to operate kernel and application clients seek entries from the table. Especially, the helper function for application is responsible for coping from user space to kernel space or vise versa.

This kernel API is used by kernel implementation. Currently, it's used for kernel clients of ALSA sequencer, while it can be used for application clients. The difference is just on address spaces of argument. In short, this kernel API can be available for application client with data in kernel space. This commit adds a document about this.
