help
Say Y or M here if your system as an ISP1760 USB host controller
or an ISP1761 USB dual-role controller.
This driver does not support isochronous transfers or OTG.
This USB controller is usually attached to a non-DMA-Master
capable bus. NXP's eval kit brings this chip on PCI card
where the chip itself is behind a PLB to simulate such
a bus.
To compile this driver as a module, choose M here: the
module will be called isp1760.

rt2x00: fix clk_get call
clk_get() takes two arguments and might return ERR_PTR(), so we
have to nullify pointer on that case, to do not break further call
to clk_get_rate().
