From 99154fd3aa9ce49f0fb842f2b07f174ae7345b64 Mon Sep 17 00:00:00 2001 From: Mathias Nyman Date: Fri, 11 Nov 2016 15:13:11 +0200 Subject: [PATCH] xhci: cleanup error message if halting the host failed. The old error message always stated that host was not halted even after trying a certain time. Host may fail the halt immediately as well with -ENODEV if device is removed and returns 0xffffffff. Use a more generic error message and show return value to know if we failed with -ETIMEDOUT or -ENODEV Signed-off-by: Mathias Nyman Signed-off-by: Greg Kroah-Hartman --- drivers/usb/host/xhci.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/drivers/usb/host/xhci.c b/drivers/usb/host/xhci.c index 1a4ca02729c2..b503189b98b0 100644 --- a/drivers/usb/host/xhci.c +++ b/drivers/usb/host/xhci.c @@ -113,12 +113,12 @@ int xhci_halt(struct xhci_hcd *xhci) ret = xhci_handshake(&xhci->op_regs->status, STS_HALT, STS_HALT, XHCI_MAX_HALT_USEC); - if (!ret) { - xhci->xhc_state |= XHCI_STATE_HALTED; - xhci->cmd_ring_state = CMD_RING_STATE_STOPPED; - } else - xhci_warn(xhci, "Host not halted after %u microseconds.\n", - XHCI_MAX_HALT_USEC); + if (ret) { + xhci_warn(xhci, "Host halt failed, %d\n", ret); + return ret; + } + xhci->xhc_state |= XHCI_STATE_HALTED; + xhci->cmd_ring_state = CMD_RING_STATE_STOPPED; return ret; }
