Subject: [PATCH 4.19 07/44] drm/msm: fix address space warning
Date: Tue, 18 Dec 2018 17:39:19 +0100 [thread overview]
Message-ID: <20181218163928.146556875@linuxfoundation.org> (raw)
In-Reply-To: <20181218163927.119623235@linuxfoundation.org>
4.19-stable review patch. If anyone has any objections, please let me know.
------------------
In the linux-4.19 stable kernel, we get a warning about a type
mismatch between phys_addr_t and dma_addr_t:
drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.c: In function '_dpu_dbg_dump_dpu_dbg_bus':
drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.c:2003:16: error: passing argument 3 of 'dma_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types]
list_size, &phys, GFP_KERNEL);
^~~~~
In file included from include/linux/dma-buf.h:31,
from drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.c:20:
include/linux/dma-mapping.h:561:15: note: expected 'dma_addr_t *' {aka 'long long unsigned int *'} but argument is of type 'phys_addr_t *' {aka 'unsigned int *'}

drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.c:2154:16: error: passing argument 3 of 'dma_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types]

This code was removed in linux-4.20 with upstream commit effec874792f
("drm/msm/dpu: Remove dpu_dbg"). Rather than backporting the large
patch, this just fixes the warning by using the correct type.
Fixes: 25fdd5933e4c ("drm/msm: Add SDM845 DPU support")
