[PATCH v5 1/5] media: platform: Fix jpeg dec driver bug and improve code quality

Xia Jiang
2019-12-04T09:44:58Z

Fix v4l2-compliance test bug and improve code quality of jpeg decode
driver, because the jpeg encode driver will base on it.

Signed-off-by: Xia Jiang <xia.jiang@mediatek.com>
---
v5: Use clamp()to replace mtk_jpeg_bound_align_image() and round_up()
to replace mtk_jpeg_align().
Get correct compose value in mtk_jpeg_selection().
Cancel spin lock and unlock operation in device run function.
Change register offset hex numberals from upercase to lowercase.

v4: new add patch for v4l2-compliance test bug fix
