Subject: Re: Fwd: dwc3: regression in USB DWC3 driver in kernel 5.15 branch

Hi. Top-posting for once, to make this easily accessible to everyone.

To Greg and everyone that might care: apparently Tomasz lost interest in
fixing this 5.15.y regression. Kinda sad, as the patches are mostly
there, but lack a S-o-b tag -- which means we are stuck here, unless
somebody else attempts a backport.

https://lore.kernel.org/all/20230904071432.32309-1-tomasz.rostanski@thalesgroup.com/

I'll thus stop tracking this regression.

#regzbot inconclusive: unfixed afaic, as patches to fix this got stuck
#regzbot ignore-activity

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
