      drivers/net: Convert compare_ether_addr to ether_addr_equal · 2e42e474
      由 Joe Perches 提交于 
      Use the new bool function ether_addr_equal to add
some clarity and reduce the likelihood for misuse
of compare_ether_addr for sorting.

      simple_open: automatically convert to simple_open() · 234e3405
      由 Stephen Boyd 提交于 
      Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op.  This leads to a
proliferation of the default_open() implementation across the entire
tree.

Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().

This replacement was done with the following semantic patch:

<smpl>
@ open @
identifier open_f != simple_open;
identifier i, f;
@@
-int open_f(struct inode *i, struct file *f)
-{
(
-if (i->i_private)
-f->private_data = i->i_private;
|
-f->private_data = i->i_private;
)
-return 0;
-}

@ has_open depends on open @
identifier fops;
identifier open.open_f;
@@
struct file_operations fops = {
...
-.open = open_f,
+.open = simple_open,
...
};
</smpl>

      iwlegacy: fix BSSID setting · e92109be
      由 Stanislaw Gruszka 提交于 
      Current commit 0775f9f9
"mac80211: remove spurious BSSID change flag" exposed bug on iwlegacy,
that we do not set BSSID address correctly and then device was not able
to receive frames after successful associate.

On the way fix scan canceling comment. Apparently ->post_associate()
do cancel scan itself, but scan cancel on BSS_CHANGED_BSSID is needed.
I'm not sure why, but when I removed it, I had frequent auth failures:

 wlan4: send auth to 54:e6:fc:98:63:fe (try 1/3)
 wlan4: send auth to 54:e6:fc:98:63:fe (try 2/3)
 wlan4: send auth to 54:e6:fc:98:63:fe (try 3/3)
 wlan4: authentication with 54:e6:fc:98:63:fe timed out

      iwlegacy: do not nulify il->vif on reset · 883a649b
      由 Stanislaw Gruszka 提交于 
      This il->vif is dereferenced in different part of iwlegacy code, so do
not nullify it. This should fix random crashes observed in companion
with microcode errors i.e. crash in il3945_config_ap().

Additionally this should address also
WARNING: at drivers/net/wireless/iwlegacy/common.c:4656 il_mac_remove_interface
at least one of the possible reasons of that warning.
