ath9k: wake hardware for interface IBSS/AP/Mesh removal
When we remove a IBSS/AP/Mesh interface we stop DMA but to do this we should ensure hardware is on. Awaken the device prior to these calls. This should ensure DMA is stopped upon suspend and plain device removal. Cc: stable@kernel.org Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.
