drm/mediatek: separate color module to fixup error memory reallocation

2017-06-27T09:34:53+00:00

Previous patch (c5f228ef6c drm/mediatek: add *driver_data for different hardware settings) calls devm_kfree() and then devm_kzalloc() to reallocate color module data structure. But this reallocation cannnot guarantee the new address is unchanged, but the caller will use the old address, which is wrong. Fix it by separate color module from general components, this patch separate color module to independent files, like mtk_disp_ovl.c and mtk_disp_rdma.c do Fixes: c5f228ef6ccd ("drm/mediatek: add *driver_data for different hardware settings") Signed-off-by: YT Shen Tested-by: Bibby Hsieh Signed-off-by: CK Hu

2017-06-27T09:34:53+00:00

If 'devm_kmalloc_array' returns NULL, we should return -ENOMEM as already done a few lines above instead of deferencing a NULL pointer a few lines below. Signed-off-by: Christophe JAILLET Reviewed-by: Matthias Brugger Signed-off-by: CK Hu

drm/mediatek: fix mtk_hdmi_setup_vendor_specific_infoframe mistake

2017-05-22T05:49:17+00:00

mtk_hdmi_setup_vendor_specific_infoframe will return before handle mtk_hdmi_hw_send_info_frame.Because hdmi_vendor_infoframe_pack returns the number of bytes packed into the binary buffer or a negative error code on failure. So correct it. Fixes: 8f83f26891e1 ("drm/mediatek: Add HDMI support") Signed-off-by: Nickey Yang Signed-off-by: CK Hu

drm/mediatek: fix a timeout loop

2017-05-22T05:49:11+00:00

This code causes a static checker warning because it treats "i == 0" as a timeout but, because it's a post-op, the loop actually ends with "i" set to -1. Philipp Zabel points out that it would be cleaner to use readl_poll_timeout() instead.
