From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit e351bf25fa373a3de0be2141b962c5c3c27006a2 upstream.
It upsets static checkers when we don't check for allocation failure. I
moved the memset() of "tv" earlier so we don't use uninitialized data on
error.
Fixes: 1d212cf0c2d8 ('[media] cx18: struct i2c_client is too big for stack')
