These two variables aren't used for anything. You should get rid of
them.

It's better to have two tests. Remove the two lines added to the
previous "if" block, and change this test to
if (config->otg || config->rwc) {

This last line seems to have gotten lost. You need to add it to
usb_hcd_omap_remove().

Not needed, since you call ohci_setup() from within ohci_omap_reset().
