Subject: [PATCH] ath9k: fix processing RXORN interrupts
|
||
|
|
|
||
|
|
The "goto chip_reset" is a bit misleading, because it does not actually
|
||
|
|
issue a chip reset. Instead it is bypassing processing of other
|
||
|
|
interrupts and assumes that the tasklet will issue a chip reset.
|
||
|
|
|
||
|
|
In the case of RXORN this does not happen, so bypassing processing of
|
||
|
|
other interrupts will simply allow them to fire again. Even if RXORN
|
||
|
|
was triggering a reset, it is not critical enough to need the bypass
|
||
|
|
here.
