====================
This is a pull request for a few early fixes for the 3.12 stream.

Alexey Khoroshilov corrects a use-after-free issue on rtl8187 found
by the Linux Driver Verification project.

Arend van Spriel provides a brcmfmac patch to fix a build issue
reported by Randy Dunlap.

Hauke Mehrtens offers a bcma fix to properly account for the storage
width of error code values before checking them.

Solomon Peachy brings a pair of cw1200 fixes to avoid hangs in that
driver with SPI devices.  One avoids transfers in interrupt context,
the other fixes a locking issue.

Stanislaw Gruszka changes the initialization of the rt2800 driver to
avoid a freeze, addressing a bug in the Red Hat bugzilla.
