From ed6cbac8ba2dd01aa12283b19243da8b66396f86 Mon Sep 17 00:00:00 2001 From: Michael Grzeschik Date: Wed, 14 Feb 2024 00:28:00 +0100 Subject: [PATCH] usb: gadget: uvc: drop unnecessary check for always set req The pump function is running in an while(1) loop. The only case this loop will be escaped is the two breaks. In both cases the req is valid. Therefor the check for an not set req can be dropped and setting the req to NULL does also has never any effect.
