i2c: designware: Synchronize IRQs when unregistering slave client
[ Upstream commit c486dcd2f1bbdd524a1e0149734b79e4ae329650 ]
Make sure interrupt handler i2c_dw_irq_handler_slave() has finished
before clearing the the dev->slave pointer in i2c_dw_unreg_slave().
There is possibility for a race if i2c_dw_irq_handler_slave() is running
on another CPU while clearing the dev->slave pointer.
