Why? What kind of bug you are fixing? You are not really describing the
problem you are trying fix.
The active_high LED of my Wistron DNMA-92 is still being recognized as
active_low on 4.7.6 mainline.
This kind of information is important, always add that to the commit log
so that we don't need to guess.
Okay, sorry about missing that before.
When I was preparing my former patch to fix that, I initially added the
PCI_DEVICE_SUB section for 0x0029/0x2096 above the PCI_VDEVICE section
for 0x0029; but then I moved the former below the latter after seeing
how 0x002A sections were sorted in the file.
I must have somehow messed up with testing, because I tested the final
version of that patch before sending it, and it was apparently working;
but now it is not working on 4.7.6 mainline.
With this patch, 0x0029/0x2096 has finally got active_high LED on
4.7.6.
I'm confused, are you now saying that this patch doesn't work?
No: the previous patch (which is already merged and added the LED driver_data
for my card) doesn't work. This one does work.
So, after seeing that the rest of the file is sorted this way (generic
section after the specific ones), I concluded that the 0x002A sorting
was wrong in the first place, and so is 0x0029. Then I sent this patch
to fix this.
I can't see how changing the order in ath_pci_id_table[] would make any
difference in functionality, but I might be missing something.
It does: I've looked through the relevant code, and found that PCI device
matching from that table is done sequentially in pci_match_id() from
drivers/pci/pci-driver.c.
So if a generic PCI_VDEVICE entry (that has both subvendor and subdevice IDs
set to PCI_ANY_ID) is put before a more specific one (PCI_DEVICE_SUB), then
the generic PCI_VDEVICE entry will match first and will be used.
And your email headers look weird:

What software are you using to send this? Only one CC header is valid
according to the spec (thanks to Luca for checking) even though mailers
seem to handle multiple CC headers. But for example my patchwork script
fails with this and uses only the first CC header.
Sorry about this, I used a custom mailer to send the patch since I was
having problems with git-send-email...
Ok, that explains it.
