Subject: mfd: max77843: Fix max77843_chg_init() return on error
From: Javier Martinez Canillas <[email protected]>
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.
