Subject: [PATCH] net: wireless: bcmdhd: remove unnecessary PCIe memory access
|
|
when BUS down.
|
|
|
|
In case PCIe BUS already down, we're not supposed to do access BAR0
|
|
area in any reason. One instance seen on test that made kernel panic.
|
|
removed disable irq calling which is useless in bus down case.
