When building this I get the following sparse warning and several kerneldoc warnings: SPARSE:drivers/media/platform/mediatek/jpeg/mtk_jpeg_dec_hw.c:661:24: warning: symbol 'mtk_jpegdec_hw_driver' was not declared. Should it be static? kerneldoc: WARNINGS drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h:127: warning: Function parameter or member 'clks' not described in 'mtk_jpegdec_clk' drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h:127: warning: Function parameter or member 'clk_num' not described in 'mtk_jpegdec_clk' drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h:178: warning: Function parameter or member 'job_timeout_work' not described in 'mtk_jpegdec_comp_dev' drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h:178: warning: Function parameter or member 'hw_param' not described in 'mtk_jpegdec_comp_dev' drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h:178: warning: Function parameter or member 'hw_state' not described in 'mtk_jpegdec_comp_dev' drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h:178: warning: Function parameter or member 'hw_lock' not described in 'mtk_jpegdec_comp_dev' drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h:219: warning: Function parameter or member 'reg_decbase' not described in 'mtk_jpeg_dev' drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h:219: warning: Function parameter or member 'dec_hw_dev' not described in 'mtk_jpeg_dev' drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h:219: warning: Function parameter or member 'is_jpgdec_multihw' not described in 'mtk_jpeg_dev' drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h:219: warning: Function parameter or member 'dec_hw_wq' not described in 'mtk_jpeg_dev' drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h:219: warning: Function parameter or member 'dec_workqueue' not described in 'mtk_jpeg_dev' drivers/media/platform/mediatek/jpeg/mtk_jpeg_core.h:219: warning: Function parameter or member 'dechw_rdy' not described in 'mtk_jpeg_dev' Can you fix this in a v8? BTW, you can also choose to combine the jpeg encoder series with this series into one single series. I'll be merging them together anyway. That's up to you, though.
