This certainly smells like a stable fix, this seems similar to this other fix:
commit 58c5296991d233f2e492aa7a884635bba478cf12

ath9k_hw: ASPM interoperability fix for AR9380/AR9382
There is an interoperability with AR9382/AR9380 in L1 state with a
few root complexes which can cause a hang. This is fixed by
setting some work around bits on the PCIE PHY. We fix by using
a new ini array to modify these bits when the radio is idle.

Without this patch I believe we will get AR9485 hanging in L1 state
with some root complexes. Can someone confirm?
Vivek, in the future can you please elaborate a little more on the
commit log entries and if its a "fix" of some sort elaborate on the
impact of not applying th patch.
Thanks,
Luis
