Hans de Goede fbca8bae1b power: supply: bq27xxx-i2c: Do not free non existing IRQ 
[ Upstream commit 2df70149e7 ]

The bq27xxx i2c-client may not have an IRQ, in which case
client->irq will be 0. bq27xxx_battery_i2c_probe() already has
an if (client->irq) check wrapping the request_threaded_irq().

But bq27xxx_battery_i2c_remove() unconditionally calls
free_irq(client->irq) leading to:

[  190.310742] ------------[ cut here ]------------
[  190.310843] Trying to free already-free IRQ 0
[  190.310861] WARNING: CPU: 2 PID: 1304 at kernel/irq/manage.c:1893 free_irq+0x1b8/0x310

Followed by a backtrace when unbinding the driver. Add
an if (client->irq) to bq27xxx_battery_i2c_remove() mirroring
probe() to fix this.
