[PATCH v2] ASoC: wm8580: Simplify probe()

[Biju Das]

Simplify probe() by replacing of_match_device->i2c_get_match_data() and
extend matching support for ID table.

While at it, remove comma in the terminator entry and simplify probe()
by replacing dev_err->dev_err_probe().

Note:
 This patch is only compile tested.

v1->v2:
 * Added Ack from Charles Keepax.
 * Removed comma in the terminator entry.
 * Restored original error code -EINVAL

This doesn't change anything functional, please do it in a separate change.

      commit: 26eacb98ca7dd3ba5a6845028a13d13a7f03123f

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
