Dave,

Here is a handful of fixes intended for 3.1.  This includes a
user-visible typo fix, a fix for a user after free in the new pn533
NFC driver, a cfg80211 fix for a possible NULL pointer dereference,
a fix for an invalid memory access in b43, and another b43 fix for
a memory corruption problem.

On top of that b43 memory corruption fix, there is a patch to remove
BROKEN from the B43_BCMA Kconfig entry, which is key to enabling
support for some of the more modern Broadcom wireless hardware.
I'm sure the Rafał (and a number of others) would love to see that
merged while the 3.1 merge window is still open as well.

Please let me know if there are problems...

Thanks!

John
