Subject: [patch] hwmon/max6697: fix memset size in max6697_init_chip()
Date: Tue, 15 Jan 2013 06:53:08 +0000	[thread overview]
Message-ID: <20130115065308.GA899@elgon.mountain> (raw)

sizeof(p) was intended instead of sizeof(data).  data is a pointer and
p is a 7 character struct.  It probably doesn't make a difference most
of the time, but it could result in using uninitialized data.
