When building an allmodconfig kernel, the following build error shows up:

Since SCSI_UFS_HWMON can't be built as a module, SCSI_UFS_HWMON has to
depend on HWMON=y.

Universal Flash Storage (UFS) is SCSI transport specification for

accessing flash storage on digital cameras, mobile phones and

consumer electronic devices.
|
|
A UFS controller communicates with a UFS device by exchanging

UFS Protocol Information Units (UPIUs).

|
UPIUs can not only be used as a transport layer for the SCSI protocol
|
|
but are also used by the UFS native command set.
|

This transport driver supports exchanging UFS protocol information units
|
|
with a UFS device. See also the ufshcd driver, which is a SCSI driver
|

that supports UFS devices.
