Sorry, I sent this before I tracked down where Andy's for-next
tree was.  It applied OK to linus/master.

IPA, which is not yet merged.

The entry in "drivers/soc/qcom/Kconfig" for this option includes
help text, so I presume it was an oversight not to include a
string (prompt).  It is the only non-trivial entry in that file
that does not include one.  Why should this entry not be listed
in menus?

I have CONFIG_IPA dependent on CONFIG_QCOM_QMI_HELPERS.  I could
change that to select it instead but I still think this entry
should be changed.

I'll mention that SLIM_QCOM_NGD_CTRL in drivers/slimbus/Kconfig
also depends on--rather than selects--QCOM_QMI_HELPERS.
