From 4d108c884b5bd5cef13fa1eb11a65eefd4c48d3f Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Thu, 27 Mar 2025 15:33:04 +0000 Subject: [PATCH] usb: xhci: annotate switch/case fallthrough properly The USB XHCI code uses an implicit switch/case fallthrough to share code for handling full speed and low speed transfers. Add our "fallthrough;" statement-like macro before the second label in the XHCI code, to avoid a warning when GCC's -Wimplicit-fallthrough warning option is enabled.
