From 0c6543f6cda442f5497b2d59ac0dcdda45f4778c Mon Sep 17 00:00:00 2001 From: Dan O'Donovan Date: Sun, 5 Feb 2017 16:30:14 +0000 Subject: spi: acpi: Initialize modalias from of_compatible When using devicetree spi_device.modalias is set to the compatible string with the vendor prefix removed. For SPI devices described via ACPI the spi_device.modalias string is initialized by acpi_device_hid. When using ACPI and DT ids this string ends up something like "PRP0001". Change acpi_register_spi_device to use the of_compatible property if present. This makes it easier to instantiate spi drivers through ACPI with DT ids.
