[ Upstream commit 512ba04d8211dd1a54dd36adc3ecc527a28069c5 ] GUID_INIT() is for internal guid_t type and shouldn't be used for the uuid_le. I.o.w. relying on the implementation details is layering violation. Use correct macros to initialize uuid_le.

mei: bus: fix unlink on bus in error path

2023-01-24T06:24:39+00:00

commit a43866856125c3c432e2fbb6cc63cee1539ec4a7 upstream. Unconditional call to mei_cl_unlink in mei_cl_bus_dev_release leads to call of the mei_cl_unlink without corresponding mei_cl_link. This leads to miscalculation of open_handle_count (decrease without increase). Call unlink in mei_cldev_enable fail path and remove blanket unlink from mei_cl_bus_dev_release.
