Subject: [PATCH] iommu/vt-d: Fix compile warning from intel-svm.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

commit e7598fac323aad0e502415edeffd567315994dd6 upstream.

The intel_svm_is_pasid_valid() needs to be marked inline, otherwise it
causes the compile warning below:

  CC [M]  drivers/dma/idxd/cdev.o
In file included from drivers/dma/idxd/cdev.c:9:0:
./include/linux/intel-svm.h:125:12: warning: ‘intel_svm_is_pasid_valid’ defined but not used [-Wunused-function]
 static int intel_svm_is_pasid_valid(struct device *dev, int pasid)
            ^~~~~~~~~~~~~~~~~~~~~~~~
