John W. Linville says: ==================== pull request: wireless 2014-12-03 One last(?) batch of fixes hoping to make 3.18... In this episode, we have another trio of rtlwifi fixes repairing a little more damage from the major update of the rtlwifi-family of drivers. These editing mistakes caused some memory corruption and missed a flag critical to proper interrupt handling. Together, these fix the kernel regression reported at https://bugzilla.kernel.org/show_bug.cgi?id=88951 by Catalin Iacob. Please let me know if there are problems! ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
