USB: cdc_subset: only build when one driver is enabled

2018-02-25T10:03:47+00:00

commit f3bb23764fac042d189129d485d3a9246cb777da upstream.

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.

net: cdc_ncm: initialize drvflags before usage

2018-02-16T19:09:36+00:00

ctx->drvflags is checked in the if clause before beeing initialized.
Move initialization before first usage.

Note, that the if clause was backported with commit 75f82a703b30
("cdc_ncm: Set NTB format again after altsetting switch for Huawei
devices") from mainline (upstream commit 2b02c20ce0c2 ("cdc_ncm: Set NTB
format again after altsetting switch for Huawei devices").  In mainline,
the initialization is at the right place before the if clause.

cx82310_eth: use skb_cow_head() to deal with cloned skbs

2018-01-17T08:35:28+00:00

commit a9e840a2081ed28c2b7caa6a9a0041c950b3c37d upstream.

We need to ensure there is enough headroom to push extra header,
but we also need to check if we are allowed to change headers.

skb_cow_head() is the proper helper to deal with this.

commit 5ee3c60c8d3b88cab6496c9b7d49a01576dd9cf9 upstream.

When the autosuspend is enabled and occurs before system suspend, we should
wake the device before running system syspend. Then, we could change the wake
event for system suspend. Otherwise, the device would resume the system when
receiving any packet.
