Subject: [PATCH 2/2] firmware: arm_scmi: remove __exit annotation
Date: Mon, 20 Sep 2021 12:02:52 +0200	[thread overview]
Message-ID: <20210920100301.1466486-2-arnd@kernel.org> (raw)
In-Reply-To: <20210920100301.1466486-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

virtio_scmi_exit() is only called from __exit function, so the annotation
is correct, but when the driver is built-in, the section gets discarded
and the reference from a callback pointer causes a link-time error:

`virtio_scmi_exit' referenced in section `.rodata' of drivers/firmware/arm_scmi/virtio.o: defined in discarded section `.exit.text' of drivers/firmware/arm_scmi/virtio.o

I could not figure out a better workaround, so let's just remove that
annotation even if it wastes a couple of bytes in .text.

Fixes: 46abe13b5e3d ("firmware: arm_scmi: Add virtio transport")
