Subject: [PATCH] hwmon: (tmp401) Fix incorrect return value of tmp401_init_client

When ti,n-factor, ti,beta-compentation are not defined in devicetree,
of_property_read_u32|s32 returns -EINVAL. In this case,
tmp401_init_client should return 0 instead of simply pass ret to its
caller.

Fixes: c825ca044988 ("hwmon: (tmp401) Add support of three advanced features")
