Subject: [PATCH][next] ixgbe: fix comparison of offset with zero or NVM_INVALID_PTR
Date: Fri, 12 Jan 2018 17:13:10 +0000	[thread overview]
Message-ID: <20180112171310.27973-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

The incorrect operator && is being used and will always return false
as offset can never be two different values at the same time. Fix this
by using the || operator instead.

Detected by CoverityScan, CID#1463806 ("Logically dead code")

Fixes: 73834aec7199 ("ixgbe: extend firmware version support")
