We don't yet support dax on reflinked files, but that is in the works.
Further, having the flag set does not automatically mean that the inode

other conditions in addition to the flag being set.
As such, we should not catch this as corruption in the verifier - simply
not actually enabling S_DAX on reflinked files is enough for now.

the assertion trips over the case where there are completely empty inobt

we advance the tracking cursor without actually putting the empty record

However, the log recovery routines don't actually check for those

There isn't any need to overwrite the mode here in the driver with what
has been detected by the firmware, such as DT or ACPI. In fact, if we
use the SPI CS gpio descriptor feature we will overwrite the mode with
SPI_MODE_0 where it already contains SPI_MODE_0 and more importantly
SPI_CS_HIGH. Clearing the SPI_CS_HIGH bit causes the CS line to toggle
when the device is probed when it shouldn't change, confusing the driver
and making it fail to probe. Drop the assignment and let the spi core
take care of it.

Expand SOF support for Alder Lake by adding ACPI machine tables
for ADL-S systems with SoundWire codecs. Modify kernel config
to choose SND_SOC_SOF_INTEL_SOUNDWIRE_LINK_BASELINE for these
platforms.
