From 5950bdc88dd1d158f2845fdff8fb1de86476806c Mon Sep 17 00:00:00 2001 From: Tom Rix trix@redhat.com Date: Mon, 14 Feb 2022 07:40:43 -0800 Subject: [PATCH] ice: initialize local variable 'tlv'

Clang static analysis reports this issues ice_common.c:5008:21: warning: The left expression of the compound assignment is an uninitialized value. The computed value will also be garbage ldo->phy_type_low |= ((u64)buf << (i * 16)); ~~~~~~~~~~~~~~~~~ ^

When called from ice_cfg_phy_fec() ldo is the uninitialized local variable tlv. So initialize.
