2.6.26 -stable review patch. If anyone has any objections, please let us know. ------------------ From: Steven Toth (cherry picked from commit d8d12b4367e2e759f65c5f9dcb94d21ec237bbc5) DVB: cx23885: Reallocated the sram to avoid concurrent VIDB/C issues This may be cx23885 chip specific and may not work on the cx23887. Analog and mpeg encoder streaming are still to be tested.
