This patch series improves type safety in the drivers/usb/* by using `min_t()` and `max_t()` instead of min(), max() with the casting inside. It should address potential type promotion issues. Scanned the current drivers/usb code with `max\(.*\(` and `min\(.*\(` regexp queries to find casting inside of min() and max() which may lead to subtle bugs or even security vulnerabilities, especially if negative values are involved. Let's refactor to min_t() and max_t() specifying the data type to ensure it's applicable for the both compareable arguments. Changes v1 -> v2: - split a single patch into a patch series per each drivers/usb/* subdirectory (Greg).
