Hi, this is your Linux kernel regression tracker. Linux-Input developers, do you have any idea what might be causing the problem outline below? It's a post 5.17 regression in mainline that was reported to bugzilla.kernel.org about a week ago, but didn't even get a single reply. Might be some other subsystem that is causing it, not sure.

Anyway, to get this tracked: #regzbot introduced: v5.17..v5.18-rc4 #regzbot from: Satadru Pramanik <satadru@xxxxxxxxx> #regzbot title: input/usb/???: bcm5974 trackpad causes error: xhci_hcd rejecting DMA map of vmalloc memory #regzbot link: https://bugzilla.kernel.org/show_bug.cgi?id=215890 Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I deal with a lot of reports and sometimes miss something important when writing mails like this. If that's the case here, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight.
