This patch just converts the function prototypes used throughout this driver to match those of the i2c framework. There is so far no functional change. This patch does not do the deeper integration of the framework bits. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Stefano Babic <sbabic@denx.de> Cc: Heiko Schocher <hs@denx.de>
