Subject: [PATCH 0/2] mwifiex: Work around firmware bugs on 88W8897 chip

Two patches which should fix all the random resets of the Marvell 88W8897 PCIe chip.
The first one works around a bug in the firmware that causes it to crash, the second
one makes us try harder to wake up the firmware before we consider it non-responsive.
More explanations in the commit messages.

Jonas Dreßler (2):
  mwifiex: Use non-posted PCI register writes
  mwifiex: Try waking the firmware until we get an interrupt
