Use usb_{alloc,free}_coherent instead of usb_buffer_{alloc,free}.
usb_buffer_alloc has been replaced with usb_alloc_coherent , and likewise usb_buffer_free has been replaced with usb_free_coherent. in kernels 2.6.34 the older names are proxies for the new ones, and in 2.6.35 the older names are gone. This patch defines the new names for the old ones, for older kernel versions. (closes issue #17383) Reported by: Chainsaw git-svn-id: http://svn.asterisk.org/svn/dahdi/linux/trunk@8762 a0bf4364-ded3-4de4-8d8a-66a801d63aff
