Subject: iommu/omap: Fix pointer cast -Wpointer-to-int-cast warnings on 64 bit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
References: bsc#1175713
Content-Transfer-Encoding: 8bit
Git-commit: f2ce16c3c15e90f8279ccda8deeb24682a4a3706
Patch-mainline: v5.7-rc1

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))
                             ^
