impl embedded_hal::digital::Error for linux_embedded_hal::gpio_cdev::Error

I'm trying to write an initialisation function for a driver, but the fact that the pin initialisation functions don't give me an embedded-hal Error trait is being a bit of a pain in the behind for me.
I can't properly incorperate the errors that arise when setting up gpios in my drivers error enum.
My situation is an SPI device that has two additional gpios, a reset and an interrupt pin.
This is a very hardware specific driver so the pins and spidev are created in the driver::new() function.
The linux_embedded_hal::spi::SPIError does implement embedded_hal::spi::Error so that one is fine I think.
Is this a workable idea?
Would the implementation in #110 solve your issue as well?
In there, the CdevPin::new method returns a CdevPinError defined in this crate instead of needing to construct the CdevPin from the external type as is currently the case.
I think yes that could very much do that.
I also think my request isn't possible, as the gpio_cdev::Error Is just a re-export so this crate doesn't influence it.
So yeah it seems like there needs to be a linux-embedded-hal way to create a pin without having to deal with gpio-cdev errors.
