smsc75xx: fix resume after device reset

2012-09-27T21:59:30Z

On some systems this device fails to properly resume after suspend, this patch fixes it by running the usbnet_resume handler. I suspect this also fixes this bug: http://code.google.com/p/chromium-os/issues/detail?id=31871 Signed-off-by: Steve Glendinning Signed-off-by: David S. Miller

net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200

2012-09-20T21:54:28Z

One of the modes of Huawei E367 has this QMI/wwan interface: I:* If#= 1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=07 Driver=(none) E: Ad=83(I) Atr=03(Int.) MxPS= 64 Ivl=2ms E: Ad=84(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms E: Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=4ms Huawei use subclass and protocol to identify vendor specific functions, so adding a new vendor rule for this combination. The Pantech devices UML290 (106c:3718) and P4200 (106c:3721) use the same subclass to identify the QMI/wwan function. Replace the existing device specific UML290 entries with generic vendor matching, adding support for the Pantech P4200. The ZTE MF683 has 6 vendor specific interfaces, all using ff/ff/ff for cls/sub/prot. Adding a match on interface #5 which is a QMI/wwan interface.

net: qmi_wwan: call subdriver with control intf only

2012-09-13T20:11:51Z

This fixes a hang on suspend due to calling wdm_suspend on the unregistered data interface. The hang should have been a NULL pointer reference had it not been for a logic error in the cdc_wdm code. commit 230718bd net: qmi_wwan: bind to both control and data interface changed qmi_wwan to use cdc_wdm as a subdriver for devices with a two-interface QMI/wwan function. The commit failed to update qmi_wwan_suspend and qmi_wwan_resume, which were written to handle either a single combined interface function, or no subdriver at all. The result was that we called into the subdriver both when the control interface was suspended and when the data interface was suspended. Calling the subdriver suspend function with an unregistered interface is not supported and will make the subdriver bug out. Signed-off-by: Bjørn Mork Signed-off-by: David S. Miller

net: qmi_wwan: fix Gobi device probing for un2430

2012-09-11T05:09:58Z

HP un2430 is a Gobi 3000 device. It was mistakenly treated as Gobi 1000 in patch b9f90eb2740203ff2592efe640409ad48335d1c2. I own this device and qmi_wwan works again with this fix. Signed-off-by: Pierre Sauter Acked-by: Bjørn Mork Signed-off-by: David S. Miller

sierra_net: Endianess bug fix.

2012-09-10T19:05:42Z

I discovered I couldn't get sierra_net to work on a powerpc. Turns out the firmware attribute check assumes the system is little endian and hence fails because the attributes is a 16 bit value. Signed-off-by: Len Sorensen Signed-off-by: David S. Miller

net: usbnet: fix softirq storm on suspend

2012-09-03T17:49:00Z

Suspending an open usbnet device results in constant rescheduling of usbnet_bh. commit 65841fd5 "usbnet: handle remote wakeup asap" refactored the usbnet_bh code to allow sharing the urb allocate and submit code with usbnet_resume. In this process, a test for, and immediate return on, ENOLINK from rx_submit was unintentionally dropped. The rx queue will not grow if rx_submit fails, making usbnet_bh reschedule itself. This results in a softirq storm if the error is persistent. rx_submit translates the usb_submit_urb error EHOSTUNREACH into ENOLINK, so this is an expected and persistent error for a suspended device. The old code tested for this condition and avoided rescheduling. Putting this test back. Cc: # v3.5 Cc: Ming Lei Cc: Oliver Neukum Signed-off-by: Bjørn Mork Signed-off-by: David S. Miller

usbnet: fix deadlock in resume

2012-08-31T20:12:21Z

A usbnet device can share a multifunction device with a storage device. If the storage device is autoresumed the usbnet devices also needs to be autoresumed. Allocating memory with GFP_KERNEL can deadlock in this case. This should go back into all kernels that have commit 65841fd5132c3941cdf5df09e70df3ed28323212 That is 3.5 Signed-off-by: Oliver Neukum CC: stable@kernel.org Signed-off-by: David S. Miller
