From mboxrd@z Thu Jan 1 00:00:00 1970 From: Archit Taneja Subject: [PATCH] omap_vout: Set DSS overlay_info only if paddr is non zero Date: Wed, 7 Mar 2012 14:31:16 +0530 Message-ID: <1331110876-11895-1-git-send-email-archit@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Sender: linux-media-owner@vger.kernel.org To: hvaibhav@ti.com Cc: tomi.valkeinen@ti.com, linux-omap@vger.kernel.org, linux-media@vger.kernel.org, Archit Taneja List-Id: linux-omap@vger.kernel.org The omap_vout driver tries to set the DSS overlay_info using set_overlay_info() when the physical address for the overlay is still not configured. This happens in omap_vout_probe() and vidioc_s_fmt_vid_out(). The calls to omapvid_init(which internally calls set_overlay_info()) are removed from these functions. They don't need to be called as the omap_vout_device struct anyway maintains the overlay related changes made. Also, remove the explicit call to set_overlay_info() in vidioc_streamon(), this was used to set the paddr, this isn't needed as omapvid_init() does the same thing later. These changes are required as the DSS2 driver since 3.3 kernel doesn't let you set the overlay info with paddr as 0.
