Subject: [PATCH 06/15] power: supply: bq24190_charger: Use i2c-core irq-mapping code
The i2c-core already maps of irqs before calling the driver's probe
function and there are no in tree users of
bq24190_platform_data->gpio_int.
Remove the redundant custom irq-mapping code and just use client->irq.
