3.11.10.4 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Mika Westerberg <[email protected]> commit 483c319188c74e82b29a0ed7a7fa7065570f2193 upstream. Commit cddb339badb0 (spi/pxa2xx: convert to dma_request_slave_channel_compat()) converted the driver to use ACPI provided DMA helpers but it forgot to initialize the platform data for the channels to -1. Failing to do so will result inadvertent match in the filter function because 0 is a valid channel number. Prevent this from happening by initializing both platform data channels correctly to -1.
