[PATCH 4.4 035/230] thermal: int340x_thermal: Fix a NULL vs IS_ERR() check
From: Greg Kroah-Hartman
Date: Fri Mar 22 2019 - 07:28:37 EST
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 3fe931b31a4078395c1967f0495dcc9e5ec6b5e3 ]
The intel_soc_dts_iosf_init() function doesn't return NULL, it returns
error pointers.
Fixes: 4d0dd6c1576b ("Thermal/int340x/processor_thermal: Enable auxiliary DTS for Braswell")
