  ipmi: kcs_bmc: Fix a memory leak in the error handling path of 'kcs_bmc_serio_add_device()' (2021-10-29 07:23:59 -0500)

----------------------------------------------------------------
Updates for the IPMI driver

A new type of low-level IPMI driver is added for direct communication
over the IPMI message bus without a BMC between the driver and the bus.

Other than that, lots of little bug fixes and enhancements.
