From 10073399cb5e389ab275bd1c9df4b486a2f0c9d4 Mon Sep 17 00:00:00 2001 From: Horatiu Vultur Date: Mon, 19 Dec 2022 09:22:15 +0100 Subject: [PATCH] net: microchip: vcap: Fix initialization of value and mask Fix the following smatch warning: smatch warnings: drivers/net/ethernet/microchip/vcap/vcap_api_debugfs.c:103 vcap_debugfs_show_rule_keyfield() error: uninitialized symbol 'value'. drivers/net/ethernet/microchip/vcap/vcap_api_debugfs.c:106 vcap_debugfs_show_rule_keyfield() error: uninitialized symbol 'mask'. In case the vcap field was VCAP_FIELD_U128 and the key was different than IP6_S/DIP then the value and mask were not initialized, therefore initialize them.
