Subject: coresight: Don't initialize variables unnecessarily
Git-commit: 0e34dc7618103e81ca77555d22493ee3e0a0e998
Patch-mainline: v5.8-rc1
References: jsc#SLE-13629,jsc#SLE-14776
These variables are assigned again before they're used. Leave them
unassigned at first so that the compiler can detect problems in the
future with use before initialization.
