Subject[PATCH] USB: rename usb_buffer_alloc() and usb_buffer_free()
Date
For more clearance what the functions actually do,

usb_buffer_alloc() is renamed to usb_alloc_coherent()
usb_buffer_free() is renamed to usb_free_coherent()

They should only be used in code which really needs DMA coherency.

All call sites have been changed accordingly, except for staging
drivers.
