Hi Takashi, Marcel,
It seems that this commit:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-4.15.y&id=7ec32f585fefd7c154453aa29ccf8fa2a11cc865
Is breaking bluetooth on some devices, see:
https://bugzilla.redhat.com/show_bug.cgi?id=1568911
The problem is the following error now being thrown:
[ 28.466248] Bluetooth: hci0: don't support firmware rome 0x1020200
Looking at the code I wonder if maybe we need to mask the ver_rom
with & 0xfff when comparing it to the qca_devices_table[i].rom_version
filed ?
Or maybe the commit is actually wrong, or maybe devices with the
0cf3:3004 USB id need either the BTUSB_QCA_ROM or BTUSB_ATH3012
quirk depending on the device and we need to probe this somehow?
I've been receiving more complaints from users about this on
various devices, so I think that the 7ec32f585fefd7c154453aa29ccf8fa2a11cc865
commit should be reverted from 4.15.x while we figure this out.
Does anyone have any idea how we cam distinguish between the 2
different versions which seem to be hiding between the same USB-id ?
4.15.y is end-of-life, so there is no more releases being made for it,
sorry.
Ah, right, no problem, Fedora should be moving to 4.16.x soon then
anyways.
But, this commit is in 4.4.y, 4.9.y, 4.14.y, and 4.16. Can you revert
it in Linus's tree and I can revert it everywhere else as well?
Takashi, do you agree that reverting this for now is best? And if so
can you please send a revert?
Regards,
Hans
