From 6d705bf9520d690ddd1411e9b4e5c7b9318528eb Mon Sep 17 00:00:00 2001 From: Sergey Shtylyov Date: Mon, 14 Feb 2022 22:56:16 +0300 Subject: [PATCH] usb: host: {e|o}hci-dbg: kill useless 'ret' variable initializers The 'ret' local variables are often initialized to 0 but this value is unused, thus we can kill those initializers...
