Subject: [PATCH] hw/i386/ich9: add comment explaining an argument to acpi_pcihp_reset call
Date: Tue, 27 Jul 2021 10:15:46 +0530	[thread overview]
Message-ID: <20210727044546.246363-1-ani@anisinha.ca> (raw)

acpi_pcihp_reset() call from ich9/pm_reset() passes an unconditional truth value
as the second argument. Added a commnet here to explain the reason why the
argument is being passed unconditionally.
