| |
pointers should be casted to unsigned long to avoid -Wpointer-to-int-cast warnings when compiling on 64-bit platform (e.g. with COMPILE_TEST):
drivers/iommu/omap-iommu.c: In function ‘omap2_iommu_enable’: drivers/iommu/omap-iommu.c:170:25: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] if (!obj->iopgd || !IS_ALIGNED((u32)obj->iopgd, SZ_16K)) ^
