drm/exynos: fix module build error

2013-07-29T17:01:53+00:00

This patch removes all MODULE_DEVICE_TABLE declarations.

Exynos drm drivers don't need to create MODULE_DEVICE_TABLE
yet because all devices of Exynos drm include in one SoC so
they cannot be plugged in as of now.

drm/exynos: exynos_drm_ipp: fix return value check

2013-07-29T17:01:53+00:00

In case of error, the function ipp_find_obj() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().

drm/exynos: remove duplicated error routine and unnecessary assign

2013-07-04T06:55:37+00:00

There were duplicated error handling routines during allocating
pages in lowlevel_buffer_allocate() and g2d_userptr_get_dma_addr().
Also unnecessary NULL assignments for variable used not any more
are removed from g2d_userptr_get_dma_addr() and
g2d_userptr_put_dma_addr().

drm/exynos: fix pages allocation size in lowlevel_buffer_allocate

2013-07-04T06:55:37+00:00

When IOMMU is not supported, buf->pages has to be allocated to
assign the result of phys_to_page() which return type is struct
page *. So it is sufficient to allocate buf->pages with the size
of multiple struct page pointers.

drm/exynos: use drm_calloc_large when allocates pointer array

2013-07-04T06:55:36+00:00

If the type of object is pointer array, the drm_calloc_large() is
more suitable than kzalloc() for its allocation function. And uses
drm_free_large() instead of kfree() also.

drm/exynos: add error check routine in exynos_drm_open

2013-07-04T06:55:36+00:00

When the exynos_drm_subdrv_open() returns error, the file_priv
should be released and file->driver_priv set to NULL.

drm/exynos: initialize the buf_num in vp_video_buffer

2013-07-04T06:55:36+00:00

The buf_num in vp_video_buffer() should be 1 or 2, but it is not
initialized, and only set to 2 in NV12M or NV12MT cases.
So this patch initializes the buf_num with 1 as default.

drm/exynos: remove dead code in vidi_power_on

2013-07-04T06:55:36+00:00

The type of input parameter enable is bool, so it does not need
to check whether true or false.
