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) ^~~~~~~~~~~~~~~~~~~~~~~~
