cdc_ncm: do not call usbnet_link_change from cdc_ncm_bind

2016-03-07T20:54:33Z

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.

cdc_ncm: toggle altsetting to force reset before setup

2016-03-07T19:37:39Z

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.

usbnet: cleanup after bind() in probe()

2016-03-07T16:40:16Z

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.

USB: cdc_subset: only build when one driver is enabled

2016-02-18T20:59:45Z

This avoids a harmless randconfig warning I get when USB_NET_CDC_SUBSET is enabled, but all of the more specific drivers are not: drivers/net/usb/cdc_subset.c:241:2: #warning You need to configure some hardware for this driver The current behavior is clearly intentional, giving a warning when a user picks a configuration that won't do anything good. The only reason for even addressing this is that I'm getting close to eliminating all 'randconfig' warnings on ARM, and this came up a couple of times. My workaround is to not even build the module when none of the configurations are enable. Alternatively we could simply remove the #warning (nothing wrong for compile-testing), turn it into a runtime warning, or change the Kconfig options into a menu to hide CONFIG_USB_NET_CDC_SUBSET.
