ACPI/IORT: Fix build error implicit-function-declaration
If CONFIG_ACPI_IORT=y and CONFIG_IOMMU_API is not set,
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-,
will be failed, like this:
drivers/acpi/arm64/iort.c: In function ‘iort_get_rmr_sids’:
drivers/acpi/arm64/iort.c:1406:2: error: implicit declaration of function ‘iort_iommu_rmr_get_resv_regions’; did you mean ‘iort_iommu_get_resv_regions’? [-Werror=implicit-function-declaration]
iort_iommu_rmr_get_resv_regions(iommu_fwnode, NULL, head);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
iort_iommu_get_resv_regions
cc1: some warnings being treated as errors
make[3]: *** [drivers/acpi/arm64/iort.o] Error 1
The function iort_iommu_rmr_get_resv_regions()
is declared under CONFIG_IOMMU_API,
and the callers of iort_get_rmr_sids() and iort_put_rmr_sids()
would select IOMMU_API.
To fix this error, move the definitions to #ifdef CONFIG_IOMMU_API.
