Subject: [PATCH] drivers: net: xgene: initialize slots
Date: Thu, 8 Dec 2016 11:17:54 +0000 [thread overview]
Message-ID: <20161208111754.9711-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
static analysis using cppcheck detected that slots was uninitialized.
Fix this by initializing it to buf_pool->slots - 1
Found using static analysis with CoverityScan, CID #1387620
Fixes: a9380b0f7be818 ("drivers: net: xgene: Add support for Jumbo frame")
