[PATCH] iommu/vt-d: Fix compile warning from intel-svm.h

From: Joerg Roedel
Date: Mon Feb 10 2020 - 04:37:03 EST


From: Joerg Roedel <jroedel@xxxxxxx>

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: âintel_svm_is_pasid_validâ defined but not used [-Wunused-function]
static int intel_svm_is_pasid_valid(struct device *dev, int pasid)
^~~~~~~~~~~~~~~~~~~~~~~~

Reported-by: Borislav Petkov <bp@xxxxxxxxx>
Fixes: 15060aba71711 ('iommu/vt-d: Helper function to query if a pasid has any active users')
