Subject: [PATCH] xen: remove redundant initialization of variable irq
Date: Thu, 11 Jun 2020 12:31:34 +0000 [thread overview]
Message-ID: <20200611123134.922395-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The variable irq is being initialized with a value that is never read
and it is being updated later with a new value. The initialization is
redundant and can be removed.
Addresses-Coverity: ("Unused value")
