Subject: [patch] [SCSI] bfa: cleanup a memcpy()
Date: Thu, 11 Oct 2012 07:02:03 +0000 [thread overview]
Message-ID: <20121011070203.GG31607@elgon.mountain> (raw)
Smatch complains that we are writing more data than ->srlid_base
member can hold. In fact, we are over writing the whole struct. I've
re-written it to be a bit more clear and to silence the static checker
warning.
