A recent change to ufshcd introduced a call to utf16s_to_utf8s, a
function that is provided by the NLS module, so we get a link error when
that is not present:
drivers/scsi/built-in.o: In function `ufshcd_read_string_desc':
:(.text+0x124d0): undefined reference to `utf16s_to_utf8s'
This adds a Kconfig 'select' statement to avoid the build error.

This selects the support for UFS devices in Linux, say Y and make

sure that you know the name of your UFS host adapter (the card
|
|
inside your computer that "speaks" the UFS protocol, also
|
|
called UFS Host Controller), because you will be asked for it.
|
|
The module will be called ufshcd.
