This series attempts to fix a part of it. From the patch description: === Subsystems like pinctrl and gpio rightfully make use of deferred probing at core level. Now, deferred drivers won't be retried if they don't have a .probe function specified in the driver struct. Fix this driver to have that, so the devices it supports won't get lost in a deferred probe. === I think it makes sense to remove platform_driver_probe from bus masters like i2c and spi (especially since they are dependant on pinctrl these days). This is what this series does. I had a look at dma drivers as well, but there are more things to be considered, so delayed for now. Please comment. If no objections are raised, I'd like to bring at least the I2C patches into v3.12, so deferred devices will then be correctly probed. The series is based on 3.12-rc4 and was compile-tested.
