ruanjinjie b8131efb89 power: supply: fix null pointer dereferencing in power_supply_get_battery_info 
[ Upstream commit 104bb8a663451404a26331263ce5b96c34504049 ]

when kmalloc() fail to allocate memory in kasprintf(), propname
will be NULL, strcmp() called by of_get_property() will cause
null pointer dereference.

So return ENOMEM if kasprintf() return NULL pointer.

Fixes: 3afb50d7125b ("power: supply: core: Add some helpers to use the battery OCV capacity table")
