From 50b81d77be31a95ba036e6403b921dc918328956 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 7 Jan 2020 22:46:37 +0100 Subject: drm: meson: fix address type confusion Casting a pointer to dma_addr_t produces a warning: drivers/gpu/drm/meson/meson_rdma.c: In function 'meson_rdma_free': drivers/gpu/drm/meson/meson_rdma.c:59:25: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] priv->rdma.addr_phys = (dma_addr_t)NULL; In this case, it's worse because the variable name has the suffix '_phys', which often indicates a phys_addr_t rather than dma_addr_t, i.e. yet another incompatible type. Change it to use consistent naming and avoid NULL.
