From 4d26ba671e3deed010311345e4426e6e11eaaf4c Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Tue, 21 Jun 2022 16:14:27 +0100 Subject: iommu: Clean up release_device checks Since .release_device is now called through per-device ops, any call which gets as far as a driver definitely *is* for that driver, for a device which has successfully passed .probe_device, so all the checks to that effect are now redundant and can be removed. In the same vein we can also skip freeing fwspecs which are now managed by core code.
