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.
