Subject: [PATCH] i2c: jz4780: drop superfluous init
Date: Sun,  5 Jun 2016 11:41:42 +0200	[thread overview]
Message-ID: <1465119702-4417-1-git-send-email-wsa@the-dreams.de> (raw)

David reported that the length for memset was incorrect (element sizes
were not taken into account). Then I saw that we are clearing kzalloced
memory, so we can simply drop this code.

Reported-by: David Binderman <dcb314@hotmail.com>
Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

Only compile tested, due to no HW.
