From 910f8d0cede74beff1eee93cf9cf2a28d7600e66 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Sat, 1 May 2010 12:20:01 -0600 Subject: USB: Change the scatterlist type in struct urb Change the type of the URB's 'sg' pointer from a usb_sg_request to a scatterlist. This allows drivers to submit scatter-gather lists without using the usb_sg_wait() interface. It has the added benefit of removing the typecasts that were added as part of patch as1368 (and slightly decreasing the number of pointer dereferences).
