Subject: [PATCH 2/6] hw/isa/vt82c686: Simplify removing unuseful qemu_allocate_irqs() call
Date: Wed, 24 Mar 2021 18:54:34 +0100 [thread overview]
Message-ID: <20210324175438.680310-3-f4bug@amsat.org> (raw)
In-Reply-To: <20210324175438.680310-1-f4bug@amsat.org>
Instead of creating an input IRQ with qemu_allocate_irqs()
to pass it as output IRQ of the PIC, with its handler simply
dispatching into the "intr" output IRQ, simplify by directly
connecting the PIC to the "intr" named output.
Fixes: 3dc31cb8490 ("vt82c686: Move creation of ISA devices to the ISA bridge")
