linux-toradex.git/drivers/net/usb, branch v4.6-rc5 Linux kernel for Apalis and Colibri modules cdc_mbim: apply "NDP to end" quirk to all Huawei devices 2016-04-15T01:04:04+00:00 Bjørn Mork bjorn@mork.no 2016-04-12T14:11:12+00:00 c5b5343cfbc9f46af65033fa4f407d7b7d98371d We now have a positive report of another Huawei device needing this quirk: The ME906s-158 (12d1:15c1). This is an m.2 form factor modem with no obvious relationship to the E3372 (12d1:157d) we already have a quirk entry for. This is reason enough to believe the quirk might be necessary for any number of current and future Huawei devices. Applying the quirk to all Huawei devices, since it is crucial to any device affected by the firmware bug, while the impact on non-affected devices is negligible. The quirk can if necessary be disabled per-device by writing N to /sys/class/net/<iface>/cdc_ncm/ndp_to_end Reported-by: Andreas Fett <andreas.fett@secunet.com> Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.

There are several bugs in this new code, for example: 1) Uses sleeping locks in get_stats64, which is not allowed, as the operation can be invoked in an atomic context. 2) Uses PM fields without CONFIG_PM or similar guards. 3) Does not synchronize HW stats when the device runtime suspends.

This reverts commit a59f8c5b048dc938fb958c91c282c865cd845705.

There are several bugs in this new code, for example:

1) Uses sleeping locks in get_stats64, which is not allowed,
   as the operation can be invoked in an atomic context.

2) Uses PM fields without CONFIG_PM or similar guards.

3) Does not synchronize HW stats when the device runtime
   suspends.

Therefore this is being reverted until a correct version
is implemented.
