The sparse tool complains as follows:
drivers/usb/host/xhci-dbgcap.c:422:18: warning:
symbol 'xhci_dbc_ring_alloc' was not declared. Should it be static?
This function is not used outside ofxhci-dbgcap.c, so this commit
marks it static.
Fixes: ac286428c69f ("xhci: dbc: don't use generic xhci ring allocation functions for dbc.")
