Subject: [PATCH] ice: initialize local variable 'tlv'
Date: Mon, 14 Feb 2022 07:40:43 -0800 [thread overview]
Message-ID: <20220214154043.2891024-1-trix@redhat.com> (raw)
From: Tom Rix <trix@redhat.com>
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 unintialized local
variable tlv. So initialize.
Fixes: ea78ce4dab05 ("ice: add link lenient and default override support")
