The patch titled lis3: SPI transport layer has been removed from the -mm tree. Its filename was lis3-spi-transport-layer.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: lis3: SPI transport layer From: Daniel Mack <daniel@xxxxxxxx> Make use of the new abstraction layer and add a new transport layer for spi. Works fine on a PXA based board.
