Subject: [PULL 07/32] hw/virtio/virtio-pci: Avoid compiler warning with -Wshadow
Date: Fri, 6 Oct 2023 13:36:32 +0200 [thread overview]
Message-ID: <20231006113657.3803180-8-armbru@redhat.com> (raw)
In-Reply-To: <20231006113657.3803180-1-armbru@redhat.com>
From: Thomas Huth <thuth@redhat.com>
"len" is used as parameter of the functions virtio_write_config()
and virtio_read_config(), and additionally as a local variable,
so this causes a compiler warning when compiling with "-Wshadow"
and can be confusing for the reader. Rename the local variables
to "caplen" to avoid this problem.
