Either this (I suspect it's this) or the subsequent patch is introducing
regressions in the ASoC tests on several of my systems in the form:

# ok 1 get_value.AT91SAMG20EK.13
# # AT91SAMG20EK.13 Inpwm8731 1-001b: ASoC error (-5): at soc_component_read_no_lock() on wm8731.1-001b for register: [0x00000004]

It's not absolutely everything but it's multiple systems (several with
Wolfson devices, plus the Pine64 Plus which has an integrated Allwinner
CODEC).  I didn't check beyond seeing the failures yet.
