I2C errors are quite common with these controllers and are non-fatal since
the transactions are retried. Silence the noisy logs so that dmesg isn't
destroyed by I2C log spam.

IRQ balancing is already performed naturally by moving the i2c IRQ to the
CPU that kicks off an i2c transaction. Therefore, opt out from IRQ
balancing operations by setting IRQF_NOBALANCING.

Hybrid mode could be switching between polling and interrupt mode. In
which case, we should always clear the pending IRQs to avoid spurious

I2C_CLASS_DEPRECATED is a flag and not an actual class.
There's nothing speaking against both, parent and child, having
I2C_CLASS_DEPRECATED set. Therefore exclude it from the check.
