Remove the use of bus_to_virt() and just fail the transfer if an unaligned buffer with no virtual address is found. AFAIK that can't happen anyway. Also change setting of coherent DMA mask to the normal 32 bits. 31 bits was only needed when calling bus_to_virt() AFAICR.

Say Y or M here if your system has a Dual Role HighSpeed
|
|
USB controller based on the DesignWare HSOTG IP Core.
|
|
|
|
If you choose to build this driver as dynamically linked
|
|
modules, the core module will be called dwc2.ko, the
|
|
PCI bus interface module (if you have a PCI bus system)
|
|
will be called dwc2_pci.ko and the platform interface module
|
|
(for controllers directly connected to the CPU) will be called
|
|
dwc2_platform.ko.
|
|
|
|
NOTE: This driver at present only implements the Host mode
|
|
of the controller. The existing s3c-hsotg driver supports
|
|
Peripheral mode, but only for the Samsung S3C platforms.
|
|
There are plans to merge the s3c-hsotg driver with this
|
|
driver in the near future to create a dual-role driver.

for which the transfer type cannot be deduced.
