| * net/usb: mark LG VL600 LTE modem ethernet interface as WWANDan Williams2011-05-111-1/+1
| | | | | | | | | | | | | | | | | | Like other mobile broadband device ethernet interfaces, mark the LG VL600 with the 'wwan' devtype so userspace knows it needs additional configuration via the AT port before the interface can be used.

| | | | | | | | | | | | | | | | | | | | Support new device OKI SEMICONDUCTOR ML7223 IOH(Input/Output Hub). The ML7223 IOH is for MP(Media Phone) use. The ML7223 is companion chip for Intel Atom E6xx series. The ML7223 is completely compatible for Intel EG20T PCH. Signed-off-by: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: David S.

| * PCH_GbE : Fixed the issue of checksum judgmentToshiharu Okada2011-05-091-5/+4
| | | | | | | | | | | | | | | | | | | | | | The checksum judgment was mistaken. Judgment result 0:Correct 1:Wrong This patch fixes the issue. Signed-off-by: Toshiharu Okada <toshiharu-linux@dsn.okisemi.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * PCH_GbE : Fixed the issue of collision detectionToshiharu Okada2011-05-091-2/+1
| | | | | | | | | | | | | | | | | | | | | | The collision detection setting was invalid. When collision occurred, because data was not resent, there was an issue to which a transmitting throughput falls. This patch enables the collision detection.

| * be2net: Fixed bugs related to PVID.Somnath Kotur2011-05-093-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | Fixed bug to make sure 'pvid' retrieval will work on big endian hosts. Fixed incorrect comparison between the Rx Completion's 16-bit VLAN TCI and the PVID. Now comparing only the relevant 12 bits corresponding to the VID. Renamed 'vid' field under Rx Completion to 'vlan_tag' to reflect accurate description. Signed-off-by: Somnath Kotur <somnath.kotur@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * ehea: fix wrongly reported speed and portKleber Sacilotto de Souza2011-05-091-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | Currently EHEA reports to ethtool as supporting 10M, 100M, 1G and 10G and connected to FIBRE independent of the hardware configuration. However, when connected to FIBRE the only supported speed is 10G full-duplex, and the other speeds and modes are only supported when connected to twisted pair.

| * ipheth: Properly distinguish length and alignment in URBs and skbsBen Hutchings2011-05-091-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB protocol this driver implements appears to require 2 bytes of padding in front of each received packet. This used to be equal to the value of NET_IP_ALIGN on x86, so the driver abused that constant and mostly worked, but this is no longer the case. The driver also mixed up the URB and packet lengths, resulting in 2 bytes of junk at the end of the skb. Introduce a private constant for the 2 bytes of padding; fix this confusion and check for the under-length case. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

However, there are a couple of places where adapter->cmd_lock is taken with softirqs enabled, lockdep warns that a softirq that tries to take mc->mca_lock could happen while adapter->cmd_lock is held, leading to an AB-BA deadlock. I'm not sure if this is a real potential deadlock or not, but the simplest and best fix seems to be simply to make sure we take cmd_lock with spin_lock_irqsave() everywhere -- the places with plain spin_lock just look like oversights. The full enormous lockdep warning is: ========================================================= [ INFO: possible irq lock inversion dependency detected ] 2.6.39-rc6+ #1

| * usbnet: runtime pm: fix out of memoryMing Lei2011-05-051-3/+7

Follows my analysis: - 'ifconfig eth0 up' brings eth0 out of suspend, and usbnet_resume is called to schedule dev->bh, then rx urbs are submited to prepare for recieving data; - some usbnet devices will produce garbage rx packets flood if info->reset is not called in usbnet_open. - so there is no enough chances for usbnet_bh to handle and release recieved skb buffers since many rx interrupts consumes cpu, so out of memory for atomic allocation in rx_submit happened. This patch fixes the issue by simply not allowing schedule of usbnet_bh until device is opened.

This was preventing us from correctly determining the mode the BIOS left the panel in for machines that neither have an OpRegion nor access to the VBT, (e.g. the EeePC 700).

This bo is then freed at card shutdown. The problem is that the ttm bo vram manager was already freed. So a crash occurs when the vga bo is freed. The fix is to free the vga bo prior to freeing the ttm bo vram manager. There might be other solutions but this seemed the simplest to me.

It also uses hcd->speed to check if a port is a USB2 protocol port. The patch fixes the issue that USB keyboard can not wakeup system from hibernation.

The root hub registered by vhci_hcd needs to have the has_tt flag set, because it can connect to low- and full-speed devices as well as high-speed devices.

| * | | | | usb: musb: gadget: Fix out-of-sync runtime pm callsJarkko Nikula2011-05-021-4/+2

This was noted on Nokia N900 where musb prevented the CPU to be able to enter deeper retention idle state. This was working in 2.6.38 before runtime pm conversions but there musb smart standby/idle modes were configured statically where they are now updated runtime depending on use and cable status. Reason for out-of-sync is that runtime pm is activated in function musb_gadget.c: usb_gadget_probe_driver but suspended only in OTG mode if cable is not connected when initializing. In peripheral only mode this leads to out-of-sync runtime pm since runtime pm remain active and is activated another time in omap2430.c: musb_otg_notifications for VBUS Connect event and thus cannot suspend for VBUS Disconnect event since the use count remains active. Fix this by moving cable status check and pm_runtime_put call in usb_gadget_probe_driver out of is_otg_enabled block.
