xhci_write_64() is essentially a wrapper for lo_hi_writeq(), but it requires struct xhci_hcd * as a parameter. Use lo_hi_writeq() directly instead No functional changes This change helps decoupling xhci and DbC Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> --- drivers/usb/host/xhci-dbgcap.c | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-)
