[ Upstream commit c064de86d2a3909222d5996c5047f64c7a8f791b ]
Fix the hardware revision numbering for Qlogic ISP1020/1040 boards. HWMASK suggests that the revision number only needs four bits, this is consistent with how NetBSD does things in their ISP driver. Verified on a IPS1040B which is seen as rev 5 not as BIT_4.

On the Asus X541UAK an unknown event 0xCF is emited when the charger is plugged in. This is caused by the following AML code:
If (ACPS ()) { ACPF = One Local0 = 0x58 If (ATKP) { ^^^^ATKD.IANE (0xCF) } } Else { ACPF = Zero Local0 = 0x57 }
Notify (AC0, 0x80) // Status Change If (ATKP) { ^^^^ATKD.IANE (Local0) }
Sleep (0x64) PNOT () Sleep (0x0A) NBAT (0x80)
Ignore the 0xCF event to silence the unknown event warning.

Commit 4ce6e2db00de ("virtio-blk: Ensure no requests in virtqueues before deleting vqs.") replaces queue quiesce with queue freeze in virtio-blk's PM callbacks. And the motivation is to drain inflight IOs before suspending.
block layer's queue freeze looks very handy, but it is also easy to cause deadlock, such as, any attempt to call into bio_queue_enter() may run into deadlock if the queue is frozen in current context. There are all kinds of ->suspend() called in suspend context, so keeping queue frozen in the whole suspend context isn't one good idea. And Marek reported lockdep warning[1] caused by virtio-blk's freeze queue in virtblk_freeze().
[1] https://lore.kernel.org/linux-block/ca16370e-d646-4eee-b9cc-87277c89c43c@sam...
Given the motivation is to drain in-flight IOs, it can be done by calling freeze & unfreeze, meantime restore to previous behavior by keeping queue quiesced during suspend.
