From ad408a1596b45868e38d0504f2ec1d5fb06f17d4 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Wed, 29 May 2019 13:54:43 -0700 Subject: Revert "usb: dwc2: host: Setting qtd to NULL after freeing it" This reverts commit b0d659022e5c96ee5c4bd62d22d3da2d66de306b. The reverted commit does nothing but adding two unnecessary lines of code. It sets a local variable to NULL in two functions, but that variable is not used anywhere in the rest of those functions. This is just confusing, so let's remove it.
