Subject: fq_codel: remove set but not used variables 'prev_ecn_mark' and
 'prev_drop_count'
Patch-mainline: v5.4-rc1
Git-commit: 018e5b458723d04cbeadbc3f0e06eba85798f427
References: bsc#1154353

Fixes gcc '-Wunused-but-set-variable' warning:

net/sched/sch_fq_codel.c: In function fq_codel_dequeue:
net/sched/sch_fq_codel.c:288:23: warning: variable prev_ecn_mark set but not used [-Wunused-but-set-variable]
net/sched/sch_fq_codel.c:288:6: warning: variable prev_drop_count set but not used [-Wunused-but-set-variable]

They are not used since commit 77ddaff218fc ("fq_codel: Kill
useless per-flow dropped statistic")
