From: Pan Bian <bianpan2...@163.com>
unction devm_regmap_init_i2c() returns an ERR_PTR on errors, and its
return value should be checked before it is dereferenced. However, in
function intel_soc_pmic_i2c_probe(), the return value of function
devm_regmap_init_i2c() is used without validation. This patch fixes it.
