This series fixes three problems Oliver pointed out during the
review of the new huawei_cdc_ncm driver:
http://patchwork.ozlabs.org/patch/278903/
That innocent driver only used cdc_mbim as a blueprint, and
all the blame should really have gone to me....
I do have a similar fix for the manage_power issue in the
cdc-wdm USB class driver as well. It will be submitted to
linux-usb as soon as Greg opens up his mailbox again :-)
Bjørn Mork (5):
net: cdc_mbim: manage_power should always set needs_remote_wakeup
net: qmi_wwan: manage_power should always set needs_remote_wakeup
net: qmi_wwan: no need to check for resume if suspend exists
net: cdc_mbim: no need to check for resume if suspend exists
net: cdc_mbim: fixup error return value
