dbg() was used a lot a long time ago to trace code flow. Now that we have ftrace, this isn't needed at all, so remove these calls.

This removes most of the dbg() calls, as they were just tracing calls, and converts the remaining ones to dev_dbg(). Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This converts the usage of dbg() to dev_dbg() where needed, and removed a bunch of these calls where they were just "tracing" calls, which are no longer needed. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Merge tag 'for-usb-next-2012-05-03' of git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-next xhci: isoc, Intel xHCI, and suspend races. Hi Greg, Here's some xHCI fixes that should be queued for 3.5. The first patch builds on Alan Stern's 3.4 patch to close the suspend and port event race conditions. It's marked for 3.4 stable, since that's where Alan's patch landed. The second patch fixes an incorrect error code that the xHCI driver would return when an isochronous transfer error occurred. The third and fourth patches fix issues seen on Intel xHCI host controllers. The third patch fixes a dead port issue that was seen on the Panther Point EHCI/xHCI host when CONFIG_USB_XHCI_HCD was turned off. The ports were being switched over to xHCI, even though the xHCI driver was never even built. The fourth patch adds support for the EHCI to xHCI port switchover for the upcoming Intel Lynx Point chipset. As I said, there's nothing here that's terribly urgent, and these patches can wait a couple weeks for the 3.5 merge window. Thanks, Sarah Sharp

Sarah Sharp authored
The upcoming Intel Lynx Point chipset includes an xHCI host controller that can have ports switched from the EHCI host controller, just like the Intel Panther Point xHCI host. This time, ports from both EHCI hosts can be switched to the xHCI host controller. The PCI config registers to do the port switching are in the exact same place in the xHCI PCI configuration registers, with the same semantics. Hooray for shipping patches for next-gen hardware before the current gen hardware is even available for purchase! This patch should be backported to stable kernels as old as 3.0, that contain commit 69e848c2 "Intel xhci: Support EHCI/xHCI port switching."

If the user chooses to say "no" to CONFIG_USB_XHCI_HCD on a system with an Intel Panther Point chipset, the PCI quirks code or the EHCI driver will switch the ports over to the xHCI host, but the xHCI driver will never load. The ports will be powered off and seem "dead" to the user. Fix this by only switching the ports over if CONFIG_USB_XHCI_HCD is either compiled in, or compiled as a module. This patch should be backported to stable kernels as old as 3.0, that contain commit 69e848c2 "Intel xhci: Support EHCI/xHCI port switching."

Hans de Goede authored
While testing unplugging an UVC HD webcam with usb-redirection (so through usbdevfs), my userspace usb-redir code was getting a value of -1 in iso_frame_desc[n].status, which according to Documentation/usb/error-codes.txt is not a valid value. The source of this -1 is the default case in xhci-ring.c:process_isoc_td() adding a kprintf there showed the value of trb_comp_code to be COMP_TX_ERR in this case, so this patch adds handling for that completion code to process_isoc_td(). This was observed and tested with the following xhci controller: 1033:0194 NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04) Note: I also wonder if setting frame->status to -1 (-EPERM) is the best we can do, but since I cannot come up with anything better I've left that as is. This patch should be backported to kernels as old as 2.6.36, which contain the commit 04e51901 "USB: xHCI: Isochronous transfer implementation".

This commit adds a bit-array to xhci bus_state for keeping track of which ports are undergoing a resume transition. If any of the bits are set when xhci_hub_status_data() is called, the routine will return a non-zero value even if no ports have any status changes pending. This will allow usbcore to handle races between root-hub suspend and port wakeup. This patch should be backported to kernels as old as 3.4, that contain the commit 879d38e6 "USB: fix race between root-hub suspend and remote wakeup".

Preston Fick authored
The original request types in the cp210x driver are labled as "DEVICE_TO_HOST" and "HOST_TO_DEVICE" but the actual bit definition corresponds to a request to the interface. This has been corrected, and the actual definition for the device requests have been added.
