[PATCH AUTOSEL 4.4 04/20] thermal: int340x_thermal: Fix a NULL vs IS_ERR() check

[Sasha Levin]

From: Dan Carpenter <dan.carpen...@oracle.com>

[ 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")
