With gentoo-sources-2.6.12-r6 and at76c503a-0.12_beta19, upon insertion or removal of my usb wifi device (Netgear MA101) I get the following output in dmesg. usb_unlink_urb() is deprecated for synchronous unlinks. Use usb_kill_urb() instead.

Normally, without the kernel debugging support included, this would lock up my system. I created a patch, and apply it before the other epatch line in the ebuild, however, I believe since it inherits the linux kernel eclass in the ebuild, that whatever kernel the usb_unlink_urb changes happened in, it could be applied that way. I am attaching a patch I generated. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Created attachment 63940 [details] patch generated against at76c503a 12_beta19 (yes i realize its misnamed)
this is fixed in at76c503a_beta23, which I now use, so I am closing as fixed.
