Linus requested in https://lkml.kernel.org/r/CAHk-=wht7kAeyR5xEW2ORj7m0hibVxZ3t+2ie8vNHLQfdbN2_g@mail.gmail.com/
that drivers should not change their behaviour on context magic like in_atomic(), in_interrupt() and so on. The USB bits were posted in https://lkml.kernel.org/r/20201019100629.419020859@linutronix.de
and merged (which is probably the same time as this patch).
I haven't look what this code should do or does but there are HCDs for which this is never true like the UHCI/OHCI controller for instance.
