Hi Erik,
your commit 53490b545cb0 ("staging: unisys: move periodic_work.c into
the visorbus directory") is in today's linux-next tree (i.e.,
next-20150511). The commit removes the Kconfig option
UNISYS_VISORUTIL but leaves one select untouched turning it into a
nop, see:
drivers/staging/unisys/visorchannel/Kconfig:7: select UNISYS_VISORUTIL
Is there a patch queued somewhere to fix this?
I detected this issue with scripts/checkkconfigsymbols.py by diffing
today's and the previous next tree.
Kind regards,
Valentin
