Subject: [PATCH] iommu: fix device remove
Date: Fri,  5 May 2017 14:08:37 -0400	[thread overview]
Message-ID: <20170505180837.11326-1-robdclark@gmail.com> (raw)

It looks like it *used* to make sense to free the device.  But now it is
embedded in 'struct iommu' (which is allocated or embedded in something
that the device allocated).

Spotted when testing qcom_iommu with CONFIG_DEBUG_TEST_DRIVER_REMOVE.

Fixes: 39ab955 ("iommu: Add sysfs bindings for struct iommu_device")
