| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The linking status may be changed when autosuspend. And, after autoresume, the driver may try to transmit packets when the device is carrier off, because the interrupt transfer doesn't update the linking status, yet. And, if the device is in ALDPS mode, the device would stop working. The another similar case is 1. unplug the cable. 2. interrupt transfer queue a work_queue for linking change. 3. device enters the ALDPS mode. 4. a tx occurs before the work_queue is called.

* net: usb: asix_devices: add .reset_resume for USB PMPeter Chen2017-01-041-0/+1
| | | | | | | | | | | The USB core may call reset_resume when it fails to resume asix device. And USB core can recovery this abnormal resume at low level driver, the same .resume at asix driver can work too. Add .reset_resume can avoid disconnecting after backing from system resume, and NFS can still be mounted after this commit. Signed-off-by: Peter Chen <peter.chen@nxp.com> Signed-off-by: David S.

* ktime: Cleanup ktime_set() usageThomas Gleixner2016-12-251-1/+1
| | | | | | | | | | ktime_set(S,N) was required for the timespec storage type and is still useful for situations where a Seconds and Nanoseconds part of a time value needs to be converted. For anything where the Seconds argument is 0, this is pointless and can be replaced with a simple assignment.

| | | | | | | | | | | | | | | | | | | | | | | | | | Telit LE922A MBIM based composition does not work properly with altsetting toggle done in cdc_ncm_bind_common. This patch adds CDC_MBIM_FLAG_AVOID_ALTSETTING_TOGGLE quirk to avoid this procedure that, instead, is mandatory for other modems.

| * net: usb: set error code when usb_alloc_urb failsPan Bian2016-12-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In function lan78xx_probe(), variable ret takes the errno code on failures. However, when the call to usb_alloc_urb() fails, its value will keeps 0. 0 indicates success in the context, which is inconsistent with the execution result. This patch fixes the bug, assigning "-ENOMEM" to ret when usb_alloc_urb() returns a NULL pointer.

It also overlapped with Jiri's change to guard the rhashtable_remove_fast() call with a check against tc_skip_sw(). 5) In mlx4, a revert bug fix in 'net' overlapped with some unrelated changes in 'net-next'. 6) In geneve, a stale header pointer after pskb_expand_head() bug fix in 'net' overlapped with a large reorganization of the same code in 'net-next'. Since the 'net-next' code no longer had the bug in question, there was nothing to do other than to simply take the 'net-next' hunks. Signed-off-by: David S. Miller <davem@davemloft.net>
