Subject: [PATCH] mfd: max77843: Fix max77843_chg_init() return on error
Date: Mon, 14 Sep 2015 10:23:11 +0200 [thread overview]
Message-ID: <1442218991-22197-1-git-send-email-javier@osg.samsung.com> (raw)
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.
Fixes: c7f585fe46d8 ("mfd: max77843: Add max77843 MFD driver core driver")
