I fail to see how the commit could cause an issue like this. Is this really reproducibly broken with the commit and irreproducible without it? As it looks like a USB/wiring problem: usb 1-2: USB disconnect, device number 2 ath: phy0: Reading Magic # failed ath: phy0: Unable to initialize hardware; initialization status: -5 ... usb 1-2: device descriptor read/64, error -110 usb 1-2: device descriptor read/64, error -71
Ccing ath9k maintainers too.
Note that this has been previously reported in: https://bugzilla.kernel.org/show_bug.cgi?id=208251 and confirmed by several people on various stable series and the mainline that the referenced commit is indeed causing the problem.
I don't get the "device descriptor read" errors though, my dmesg is posted on the bug report, it just says "ath9k_htc: Failed to initialize the device".
I don't have so much info about the HW, besides a dmesg showing the phy breaking. I also added the reporter to CC too.

If you need more info, please let me know and I'll try my best to get it as fast as possible for you.
