commit 444ff00734f3878cd54ddd1ed5e2e6dbea9326d5 upstream.
devm_request_threaded_irq() requested IRQs are only free-ed after the driver's remove function has ran. So the IRQ could trigger and call bq27xxx_battery_update() after bq27xxx_battery_teardown() has already run.
Switch to explicitly free-ing the IRQ in bq27xxx_battery_i2c_remove() to fix this.
