Yang Yingliang 12c4673204 power: supply: max17040: fix null-ptr-deref in max17040_probe() 
[ Upstream commit 1d422ecfc48ee683ae1ccc9217764f6310c0ffce ]

Add check the return value of devm_regmap_init_i2c(), otherwise
later access may cause null-ptr-deref as follows:

KASAN: null-ptr-deref in range [0x0000000000000360-0x0000000000000367]
RIP: 0010:regmap_read+0x33/0x170
