drivers/usb/misc: refactor min with min_t

2024-11-13T14:09:51+00:00

Ensure type safety by using min_t() instead of min().

usb: usbtest: fix a type promotion bug

2023-10-08T05:50:36+00:00

The "len" here is sometimes negative error codes from usb_get_descriptor(), so we don't want to type promote them to unsigned long. This bug pre-dates the invention of git.
