[PATCH 5.8 10/56] hinic: bump up the timeout of SET_FUNC_STATE cmd

From: Greg Kroah-Hartman
Date: Fri Sep 25 2020 - 08:50:04 EST


From: Luo bin <luobin9@xxxxxxxxxx>

[ Upstream commit 4e4269ebe7e18038fffacf113e2dd5ded6d49942 ]

We free memory regardless of the return value of SET_FUNC_STATE
cmd in hinic_close function to avoid memory leak and this cmd may
timeout when fw is busy with handling other cmds, so we bump up the
timeout of this cmd to ensure it won't return failure.
