It doesn't really matter that the error codes are different, it matters that they are meaningful. As much as possible you should pass error codes from the lower layers. parport_claim_or_block() and i2c_bit_add_bus() return proper error codes so you should record and transmit them.
Oh, surely yes. I assumed they don't and this series is a first step to fix this. Should have looked myself. Thanks for jumping in here.
