[alsa-lib][PATCH v2 0/3] timer/hwdep: update included headers with UAPI headers in recent kernel

[alsa-lib][PATCH v2 0/3] timer/hwdep: update included headers with UAPI headers in recent kernel

[Takashi Sakamoto]

Hi,

In this subsystem, interfaces between kernel/userspace are described in
UAPI headers of kernel source. User space library (alsa-lib) includes
this header as its code base. When developers update UAPI headers in
development cycle of kernel, corresponding headers in alsa-lib should be
updated synchronously.

The purpose of this patchset is to catch up recent UAPI header for
userspace library. There're missing changes added at v4.7, v4.9 and v4.12
development period.

v2 changes:
 - Update commit description.
 - Reorder commits so that aligned according to date of corresponding code
   change.

  timer: obsolete legacy rtctimer instance
  hwdep: add Line6 USB series support
  hwdep: add support for MOTU FireWire series and RME Fireface series

[alsa-lib][PATCH v2 1/3] timer: obsolete legacy rtctimer instance

[Takashi Sakamoto]

At v4.7 development, ALSA timer interface dropped device instance based on
legacy rtctimer implementation. User space applications should not use the
device instance.

This commit adds comments to notify a corresponding macro should not be
used anymore.

[alsa-lib][PATCH v2 2/3] hwdep: add Line6 USB series support

[Takashi Sakamoto]

Drivers for Line6 USB series was firstly added to staging directory at
development period of v2.6.30 kernel. At v4.9 kernel development, they
were moved to sound directory. The drivers include HwDep interface, while
header in user space library has never been updated for an entry
corresponding to the drivers.

This commit adds the entry.

[alsa-lib][PATCH v2 3/3] hwdep: add support for MOTU FireWire series and RME Fireface series

[Takashi Sakamoto]

Drivers for MOTU FireWire series and RME Fireface series were newly added
to v4.12 kernel. Like the other drivers in ALSA firewire stack, they also
support HwDep interface.

This commit add entries for the drivers.

Applied all three patches now.  Thanks.
