Subject: [PATCH] drm/exynos: fix size_t format string
Date: Wed, 27 May 2026 21:45:07 +0200 [thread overview]
Message-ID: <20260527194525.45762-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb•de>
The exynos_gem->base.size argument is a size_t rather than an
unsigned long, so adapt the printk() format string accordingly:
In file included from drivers/gpu/drm/exynos/exynos_drm_gem.c:16:
drivers/gpu/drm/exynos/exynos_drm_gem.c: In function 'exynos_drm_alloc_buf':
drivers/gpu/drm/exynos/exynos_drm_gem.c:69:49: error: format '%lx' expects argument of type 'long unsigned int', but argument 6 has type 'size_t' {aka 'unsigned int'} [-Werror=format=]
69 | DRM_DEV_DEBUG_KMS(drm_dev_dma_dev(dev), "dma_addr(0x%lx), size(0x%lx)\n",
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
70 | (unsigned long)exynos_gem->dma_addr, exynos_gem->base.size);
| ~~~~~~~~~~~~~~~~~~~~~
| |
| size_t {aka unsigned int}
The dma_addr in the same line is already printed using a cast
to unsigned long, so change that similarly to use the correct
%pad format.
Fixes: 11e898373fba ("drm/exynos: Drop exynos_drm_gem.size field")
