qmi_wwan: add another Lenovo EM74xx device ID

2017-06-07T10:01:51+00:00

[ Upstream commit 486181bcb3248e2f1977f4e69387a898234a4e1e ] In their infinite wisdom, and never ending quest for end user frustration, Lenovo has decided to use a new USB device ID for the wwan modules in their 2017 laptops. The actual hardware is still the Sierra Wireless EM7455 or EM7430, depending on region. Signed-off-by: Bjørn Mork Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

cdc_ncm: do not call usbnet_link_change from cdc_ncm_bind

2017-05-20T12:18:44+00:00

commit 4d06dd537f95683aba3651098ae288b7cbff8274 upstream. usbnet_link_change will call schedule_work and should be avoided if bind is failing. Otherwise we will end up with scheduled work referring to a netdev which has gone away. Instead of making the call conditional, we can just defer it to usbnet_probe, using the driver_info flag made for this purpose.

usbnet: cleanup after bind() in probe()

2016-07-12T12:47:31+00:00

[ Upstream commit 1666984c8625b3db19a9abc298931d35ab7bc64b ] In case bind() works, but a later error forces bailing in probe() in error cases work and a timer may be scheduled. They must be killed. This fixes an error case related to the double free reported in http://www.spinics.net/lists/netdev/msg367669.html and needs to go on top of Linus' fix to cdc-ncm.

cdc_ncm: toggle altsetting to force reset before setup

2016-07-12T12:47:31+00:00

[ Upstream commit 48906f62c96cc2cd35753e59310cb70eb08cc6a5 ] Some devices will silently fail setup unless they are reset first. This is necessary even if the data interface is already in altsetting 0, which it will be when the device is probed for the first time. Briefly toggling the altsetting forces a function reset regardless of the initial state. This fixes a setup problem observed on a number of Huawei devices, appearing to operate in NTB-32 mode even if we explicitly set them to NTB-16 mode. Signed-off-by: Bjørn Mork Signed-off-by: David S.
