From d697cdda43939a80432863e2e26df6701ce72b63 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Tue, 27 Oct 2009 15:18:46 -0400 Subject: [PATCH] USB: don't use a fixed DMA mapping for hub status URBs This patch (as1296) gets rid of the fixed DMA-buffer mapping used by the hub driver for its status URB. This URB doesn't get used much -- mainly when a device is plugged in or unplugged -- so the dynamic mapping overhead is minimal. And most systems have many fewer external hubs than root hubs, which don't need a mapped buffer anyway. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman --- Reading git-format-patch failed
