Subject: [patch] bfa: use strncpy() instead of memcpy()
Date: Sat, 30 Jan 2016 17:36:03 +0300 [thread overview]
Message-ID: <20160130143603.GB3462@mwanda> (raw)
BFA_MFG_NAME is "QLogic" which is only 7 bytes, but we are copying 8
bytes. It's harmless because the badding byte is likely zero but it
makes static checkers complain.
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>

Technically the memset() is not needed because strncpy() will pad the
rest of the buffer with zeros but I was worried that people would be
paranoid.
