From f61c5c830ff0c906907a73a4bfddba6a8f91cbcb Mon Sep 17 00:00:00 2001 From: Jakob Koschel Date: Thu, 24 Mar 2022 08:31:51 +0100 Subject: misc: vmw_vmci: replace usage of found with dedicated list iterator variable To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body. To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean [1]. This removes the need to use a found variable and simply checking if the variable was set, can determine if the break/goto was hit.
