From 9a83190300867fb024d53f47c31088e34188efc1 Mon Sep 17 00:00:00 2001 From: Guido Kiener Date: Tue, 25 Sep 2018 01:30:31 +0200 Subject: [PATCH] usb: usbtmc: uninitialized symbol 'actual' in usbtmc_ioctl_clear Fix uninitialized symbol 'actual' in function usbtmc_ioctl_clear. When symbol 'actual' is not initialized and usb_bulk_msg() fails, the subsequent kernel debug message shows a random value.
