Subject: [PULL 29/30] spapr: Pass sPAPR machine state to some RTAS events handling functions
Date: Fri, 11 Dec 2020 15:15:06 +1100	[thread overview]
Message-ID: <20201211041507.425378-30-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20201211041507.425378-1-david@gibson.dropbear.id.au>

From: Greg Kurz <groug@kaod.org>

Some functions in hw/ppc/spapr_events.c get a pointer to the machine
state using qdev_get_machine(). Convert them to get it from their
caller when possible.
