Subject: power: supply: isp1704: Fix unchecked return value of devm_kzalloc

From: Pan Bian <[email protected]>

[ Upstream commit 8b20839988f1ed5e534b270f3776709b640dc7e0 ]

Function devm_kzalloc() will return a NULL pointer. However, in function isp1704_charger_probe(), the return value of devm_kzalloc() is directly used without validation. This may result in a bad memory access bug.
