xhci: dbc: Don't pass the xhci pointer as a parameter to xhci_dbc_init_context() (1da49a26) · Commits · 戴 / test

xhci_dbc_init_context() no longer needs the struct xhci_hcd pointer. Pass the dbc pointer directly instead. No functional changes This change helps decoupling xhci and DbC Signed-off-by:
