X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=87e837b6dd8f7756ac55325900ff885f1689dc71;p=karo-tx-linux.git

ipmi: Reset the KCS timeout when starting error recovery

commit eb6d78ec213e6938559b801421d64714dafcf4b2 upstream.

The OBF timer in KCS was not reset in one situation when error recovery
was started, resulting in an immediate timeout.
