-stable review patch. If anyone has any objections, please let us know. ------------------ From: Oliver Endriss V4L: saa7146: Fix allocation of clipping memory Olaf Hering pointed out that SAA7146_CLIPPING_MEM would become very large for PAGE_SIZE > 4K. In fact, the number of clipping windows is limited to 16, and calculate_clipping_registers_rect() does not use more than 256 bytes. SAA7146_CLIPPING_MEM adjusted accordingly.
