From 0c4a1590189b426814748d2e03b95541852b3af6 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 11 May 2011 00:09:30 +0200 Subject: spi: Use void pointers for data in simple SPI I/O operations Currently the simple SPI I/O operations all take pointers to u8 * buffers to operate on. This creates needless type compatibility issues and the underlying spi_transfer structure uses void pointers anyway so convert the API over to take void pointers too.
