Hence the code in the if condition gets executed. Then in "exit" section ret is set again to non-zero value. The program jumps back to the exit label and the code in the if condition gets executed again leading to an infinite loop. Removing the goto exit line will avoid the possible infinite loop forming when kmalloc fails. Change-Id: I0d7d7d3d6d65806ede866667a7030fb9d1e0480e Signed-off-by: Harsh Sahu <hsahu@codeaurora.org>

Fix it by adding the buffer to a cleanup queue after mapping and unmap/free the buffer in the work queue after cwb intr done.

But this still leaves possibility of race condition based on iommu_attached status flag. -> Display thread finishes the attach and releases the iommu lock -> DCS cmd thread gets the iommu lock and checks iommu_attached status before display thread could change it.

This was seen when WB is using the same mixer which was earlier used by HDMI, with 3D Mux enabled. Since 3D Mux registers are double buffered, the best way to clear control operations is to re-use the control path. Hence allowing WB to choose the first available control path.

So the number of displays are calculated as 2 whereas the driver considers this as a single display. This causes MDP clocks to remain ON. This change corrects number of displays calculated by checking for split display.
