[PATCH v3 0/2] soundwire: sysfs: expose device number and status

[Pierre-Louis Bossart]

This patchset combines three contributions:

Srinivas Kandagalta suggested creating a device even it's detected on
the bus but not described in platform firmware. I suggested adding the
device number and status to show the difference with 'ghost' devices,
described in firmware but not physically present. Vinod suggested a
simpler way to report the status.

I did not keep Vinod's patch separate since it was using the same
group attribute as the other properties, which prevents status and
device number from being reported if there is no firmware and no
driver.

These patches were tested on Qualcomm and Intel platforms.

v3: add Co-developed-by tags and move 'status' and 'device_number' to
device level instead of a dev-status directory.

v2: as suggested by GregKH, add attribute group by default by setting
the groups pointer at the device level.
