For 5.15 attempting to use an ax88179_178a adapter "0b95:1790 ASIX
Electronics Corp. AX88179 Gigabit Ethernet"
started causing crashes.
This did not reproduce in the 6.6 kernel.
The crashes were narrowed down to the following two commits brought
into v5.15.146:
commit d63fafd6cc28 ("net: usb: ax88179_178a: avoid failed operations
when device is disconnected")
commit f860413aa00c ("net: usb: ax88179_178a: wol optimizations")
Those two use an uninitialized pointer `dev->driver_priv`.
In later kernels this pointer is initialized in commit 2bcbd3d8a7b4
("net: usb: ax88179_178a: move priv to driver_priv").
Picking in the two following commits fixed the issue for me on 5.15:
commit 9718f9ce5b86 ("net: usb: ax88179_178a: remove redundant init code")
commit 2bcbd3d8a7b4 ("net: usb: ax88179_178a: move priv to driver_priv")
The commit 9718f9ce5b86 ("net: usb: ax88179_178a: remove redundant
init code") was required for
the fix to apply cleanly.
