This patch removes unnecessary pm suspend/resume functions. All kms sub drivers will be controlled by top of Exynos drm driver and connector dpms so these sub drivers shouldn't have their own pm interfaces. Signed-off-by:

Gustavo Padovan authored
The only thing mode_fixup was doing was set the adjusted_mode->vrefresh to 60, but it already has the value of 60 when the decon_mode_fixup() is called. That means this call is actually pointless and can be removed. Signed-off-by:

When obj->import_attach is existed, code calling drm_prime_gem_destroy() was removed from commit 67e93c80 ("drm/exynos: stop copying sg table"), and it's a fault. The drm_prime_gem_destroy() is cleanup function which GEM drivers need to call when they use drm_gem_prime_import() to import dma-bufs, so exynos-drm driver using drm_gem_prime_import() needs calling drm_prime_gem_destroy().

There is no guarantee that DMA addresses are the same as physical addresses, but dma_to_pfn() knows how to convert a dma_addr_t to a PFN which can then be converted to a struct page. Suggested-by:

mgag200_driver_load's error path just calls the drm driver's driver_unload op. It isn't safe to call this because it doesn't handle things well if driver_load fails somewhere mid way. Replace the call to mgag200_driver_unload with a more finegrained error handling path. Link: http://lkml.kernel.org/r/55F6E68D.8070800@codeaurora.orgReported-by:

we used to adopt wait_reg_mem to let CE wait before DE finish page updating, but from Tonga+, CE doesn't support wait_reg_mem package so this logic no longer works. so here is another approach to do same thing: Insert two of SWITCH_BUFFER at both front and end of vm_flush can guarantee that CE not go further to process IB_const before vm_flush done. Insert two of SWITCH_BUFFER also works on CI, so remove legency method to sync CE and ME v2: Insert double SWITCH_BUFFER at front of vm flush as well. Signed-off-by:

The amdgpu_cs_parser_init() function doesn't clean up after itself but instead the caller uses a free everything function amdgpu_cs_parser_fini() on failure. This style of error handling is often buggy. In this example, we call "drm_free_large(parser->chunks[i].kdata);" when it is an unintialized pointer or when "parser->chunks" is NULL. I fixed this bug by adding unwind code so that it frees everything that it allocates. I also mode some other very minor changes: 1) Renamed "r" to "ret". 2) Moved the chunk_array allocation to the start of the function. 3) Removed some initializers which are no longer needed.
