Subject: eal/windows: fix vfprintf warning with clang
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=498ec3c6da6da0a8c9e6ad7ddd087e10faa77eb0;p=dpdk.git

eal/windows: fix vfprintf warning with clang

When building with clang (11.0,--buildtype=debug), eal_lcore.c
produces a -Wformat-nonliteral warning from the vfprintf call
in log_early.

Add __rte_format_printf annotation.

Fixes: b8a36b086625 ("eal/windows: improve CPU and NUMA node detection")
