--- Comment #1 from Wei Huang ([email protected]) --- Hi kakapapa2,
Thanks for reporting this. A fix has been submitted to the linux-usb mailing list:
https://lore.kernel.org/linux-usb/?q=huangwei%40kylinos.cn
The fix mirrors the equivalent dwc3 fix (commit e6bdf8195b4a) by switching hsotg->regset from devm_kzalloc() to kzalloc() and freeing it explicitly in dwc2_debugfs_exit().
