Bugzilla 605. Fix tearing when VPU rotates images.2.6.22-mx27ads-2007102503272.6.22-mx27-200710250327
Patch for Bugzilla 605. Fix tearing when VPU rotates images.
A diagonal line appears when the VPU rotates the picture,
at the encode stage. The PRP driver updates the buffer
addresses while the PRP is processing data.
Applies to linux 2.6.22 kernel for MX27 platform.
