[ Upstream commit 23dc958689449be85e39351a8c809c3d344b155b ]

The very quiet and distorted headphone output bug that afflicted my
Samsung Notebook 9 is appearing in many other Samsung laptops. Expose
the quirk which fixed my laptop as a model so other users can try it.

[ Upstream commit f082bb59b72039a2326ec1a44496899fb8aa6d0e ]

The driver supports WM1811, WM8994, WM8958 devices but according to
documentation and the regmap definitions the WM8958_DSP2_* registers
are only available on WM8958. In current code these registers are
being accessed as if they were available on all the three chips.

When starting playback on WM1811 CODEC multiple errors like:
"wm8994-codec wm8994-codec: ASoC: error at soc_component_read_no_lock on wm8994-codec: -5"
can be seen, which is caused by attempts to read an unavailable
WM8958_DSP2_PROGRAM register. The issue has been uncovered by recent
commit "e2329ee ASoC: soc-component: add soc_component_err()".

This patch adds a check in wm8958_aif_ev() callback so the DSP2 handling
is only done for WM8958.

[ Upstream commit d8d0db7bb358ef65d60726a61bfcd08eccff0bc0 ]

Some devices have broken extension unit where getting current value
doesn't work. Attempt that once when creating mixer control for it. If
it fails, just ignore it, so that it won't cripple the device entirely
(and/or make the error floods).
