Subject: [patch] bnx2x: use strlcpy() to copy a string
Date: Tue, 2 Oct 2012 14:47:46 +0300 [thread overview]
Message-ID: <20121002114746.GB1413@elgon.mountain> (raw)
DRV_MODULE_VERSION is smaller than the ->version buffer so the memcpy()
copies 1 byte past the end of the string. It's not super harmful, but
it makes the static checkers complain.
