4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Javier Martinez Canillas <javier@osg.samsung.com>

commit 1b52e50f2a402a266f1ba2281f0a57e87637a047 upstream.

If i2c_new_dummy() fails in max77843_chg_init(), an PTR_ERR(NULL) is
returned which is 0. So the function was wrongly returning a success
value instead of an error code.
