Subject: [RESEND PATCH 2/4] iommu/omap: Fix printing format for size_t on 64-bit
Date: Tue,  3 Mar 2020 21:27:49 +0100	[thread overview]
Message-ID: <20200303202751.5153-2-krzk@kernel.org> (raw)
In-Reply-To: <20200303202751.5153-1-krzk@kernel.org>

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=]

Acked-by: Suman Anna <s-anna@ti.com>
