[PATCH v2 3.6 1/6] ath9k_hw: do not enable the MIB interrupt in the interrupt mask register

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The interrupt is no longer handling it. While it shouldn't fire (wraparound
is highly unlikely), the consequences would be fatal (interrupt storm).
Disable the interrupt to prevent that from happening.
