The percpu subsystems point is to enable the use of special hardware
instructions that can perform address calculat

snd_soc_pcm_stream.formats should use the bitmask SNDRV_PCM_FMTBIT_*
instead of the sequential integers SNDRV_PCM_FORMAT_* as explained by
commit e712bfca1ac1f63f622f87c2f33b57608f2a4d19
("ASoC: codecs: use SNDRV_PCM_FMTBIT_* for format bitmask").

INIT_IPS and GATE_STATE fields have a wrong offset in SG_CONFIG_REG_3.
This register is used by stream gate control of PSFP, and it has not
been used before, because PSFP is not implemented in ocelot driver.

This change is mostly cosmetic, but it's also a pre-cursor to the
the change for 'iio_buffer_set_attrs()', where the helper gets updated to
better support multiple IIO buffers for 1 IIO device.
The only functional change is that the error message for the trigger alloc
failure is bound to the paren

Is there a reason you created your own
While iterating over child nodes with the for_each functions, if
control is transferred from the middle of the loop, as in the case
of a break or return or goto, there is no decrement in the
reference counter thus ultimately resulting in a memory leak.
