The motivation is to not give driver authors a reason to (wrongly) believe that returning an error code was sensible error handling. In fact the spi core only emits a warning message in this case and otherwise continues as if the return value was zero. This usually yields resource leaks that sometimes can lead to exceptions later on. The atmel-quadspi driver is one of these drivers that got error handling wrong, this is fixed here and in the last patch the driver is converted to .remove_new() with the eventual goal to change .remove() to return void once all drivers are converted this way.
