[PATCH 5.16 054/164] ice: initialize local variable tlv

[Greg Kroah-Hartman]

From: Tom Rix <trix@xxxxxxxxxx>

commit 5950bdc88dd1d158f2845fdff8fb1de86476806c upstream.

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.
