It will print out that the case happens in SSIF_BAD_SMBUS state always
because ssif_bmc->state is already assigned as SSIF_BAD_SMBUS above.
Move the assignment to after the dev_warn printing.

Does this driver have any Ampere specific handling? If not, it could be
"ssif-bmc" as a generic SSIF driver.

Add 'MODULE_DEVICE_TABLE(of, ssif_bmc_match);'
