ipmi: kcs_bmc: coding-style fixes
OpenBMC-Staging-Count: 1 Signed-off-by: Haiyue Wang <haiyue.wang@linux.intel.com> Signed-off-by: Corey Minyard <cminyard@mvista.com> [This is is not the same commit as upstream, as the changes to use new type '__poll_t' from linux-4.16-rc1 are not included. This was done because the feature is not a small self contained backport. There is no impact on functionality for dev-4.13] Signed-off-by: Joel Stanley <joel@jms.id.au>
