[PATCH 0/4] fix unused-but-set-global warnings

[Stephen Hemminger <stephen@networkplumber.org>]

  Clang 23 adds -Wunused-but-set-global, which reports file scope
  variables that are assigned but never read. It is enabled by -Wall and
  does not appear with gcc or with clang 20 through 22.

  Three of these are dead variables and are simply removed. The fourth,
  'alive' in dpaa_of.c, is a real debug aid: it is only read by
  DPAAX_HWWARN, which discards its condition when RTE_LIBRTE_DPAAX_DEBUG
  is not defined. That one is fixed by making the empty expansion consume
  its argument, which keeps the condition compiled in both builds and
  covers every other DPAAX_HWWARN user as well.

  The patches are independent and touch four unrelated drivers.

Stephen Hemminger (4):
  common/dpaax: fix unused variable warning in non-debug build
  bus/dpaa: remove unused qman_clk variable
  common/zsda: remove unused device counter
  net/qede: remove unused app version variable
