Hi,
In drivers/usb/dwc2/debugfs.c line 790:
https://web.git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/usb/dwc2/debugfs.c?h=v6.13.9
790:
hsotg->regset = devm_kzalloc(hsotg->dev, sizeof(*hsotg->regset),
GFP_KERNEL);
"hsotg->regset" is allocated but not be released in dwc2_debugfs_exit().
FYI.
dwc3 was fixed same issue in commit e6bdf8195b4a43ebff71f25fc7ca5e436e79161a.
