Subject: iommu/omap: Fix printing format for size_t on 64-bit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
References: bsc#1175713
Content-Transfer-Encoding: 8bit
Git-commit: 6135a891dc0bc43265cd583614419e04f3fd42b4
Patch-mainline: v5.7-rc1

Print size_t as %zu or %zx to fix -Wformat warnings when compiling on
64-bit platform (e.g. with COMPILE_TEST):

    drivers/iommu/omap-iommu.c: In function ‘flush_iotlb_page’:
    drivers/iommu/omap-iommu.c:437:47: warning:
        format ‘%x’ expects argument of type ‘unsigned int’,
        but argument 7 has type ‘size_t {aka long unsigned int}’ [-Wformat=]
