Subject: [PATCH] spi: update modalias_show after of_device_uevent_modalias
support
Commit 3ce6c9e2617e ("spi: add of_device_uevent_modalias support") is
incomplete, as it didn't update the modalias_show function to generate the
of: modalias string if available.
Fixes: 3ce6c9e2617e ("spi: add of_device_uevent_modalias support")
