      nxp-nci: i2c: Do not check specifically for -EREMOTEIO error · 59df9bb2
      由 Fabio Estevam 提交于 
      Function nxp_nci_i2c_write currently assumes in case of
I2C bus NACK that the NFC device is in stand-by mode and
will retry the I2C transaction after a pause. This assumes
that the first failed I2C transaction will wake-up the device.

This is done by checking on EREMOTEIO, which is wrong. According
to Documentation/i2c/fault-codes ENXIO shall be used. Unfortunately
the NOACK return code is currently inconsistent across various I2C
host controller drivers. So only check for the generic error case
instead.

This is a temporary fix. As soon as all I2C bus master drivers are
fixed to consistently return 'ENXIO', then we can do the specific
error check again.

      net/core: revert "net: fix __netdev_update_features return.." and add comment · 17b85d29
      由 Nikolay Aleksandrov 提交于 
      This reverts commit 00ee5927 ("net: fix __netdev_update_features return
on ndo_set_features failure")
and adds a comment explaining why it's okay to return a value other than
0 upon error. Some drivers might actually change flags and return an
error so it's better to fire a spurious notification rather than miss
these.

      af_unix: take receive queue lock while appending new skb · a3a116e0
      由 Hannes Frederic Sowa 提交于 
      While possibly in future we don't necessarily need to use
sk_buff_head.lock this is a rather larger change, as it affects the
af_unix fd garbage collector, diag and socket cleanups. This is too much
for a stable patch.

For the time being grab sk_buff_head.lock without disabling bh and irqs,
so don't use locked skb_queue_tail.

      rtnetlink: fix frame size warning in rtnl_fill_ifinfo · b22b941b
      由 Hannes Frederic Sowa 提交于 
      Fix the following warning:

  CC      net/core/rtnetlink.o
net/core/rtnetlink.c: In function ‘rtnl_fill_ifinfo’:
net/core/rtnetlink.c:1308:1: warning: the frame size of 2864 bytes is larger than 2048 bytes [-Wframe-larger-than=]
 }
 ^
by splitting up the huge rtnl_fill_ifinfo into some smaller ones, so we
don't have the huge frame allocations at the same time.
