[PATCH 3.12 50/83] [media] drivers: media: usb: b2c2: use usb_*_coherent() instead of pci_*_consistent() in flexcop-usb.c

[Jiri Slaby]

From: Chen Gang <gang.chen@xxxxxxxxxxx>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 6c7e346974ad6d20898026f209581fb6dd8ce3f0 upstream.

Some architectures do not support PCI, but still support USB, so need
let our usb driver try to use usb_* instead of pci_* to support these
architectures, or can not pass compiling.
The related error (with allmodconfig for arc):
    CC [M]  drivers/media/usb/b2c2/flexcop-usb.o
