Hi all,
After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:
drivers/gpu/drm/drm_gem_cma_helper.c: In function 'drm_gem_cma_buf_destroy':
drivers/gpu/drm/drm_gem_cma_helper.c:38:2: error: implicit declaration of function 'dma_free_writecombine' [-Werror=implicit-function-declaration]
drivers/gpu/drm/drm_gem_cma_helper.c: In function 'drm_gem_cma_create':
drivers/gpu/drm/drm_gem_cma_helper.c:61:2: error: implicit declaration of function 'dma_alloc_writecombine' [-Werror=implicit-function-declaration]
Probably caused by commit 16ea975eac67 ("drm/tilcdc: add TI LCD
Controller DRM driver (v4)") which forced CONFIG_DRM_GEM_CMA_HELPER to
'y'. dma_alloc/free_writecombine are only defined on ARM.
I added this patch for today.
