From: Christophe JAILLET Date: Tue, 23 May 2023 18:17:52 +0000 (+0200) Subject: net/mlx4: Use bitmap_weight_and() X-Git-Tag: v6.6.17~4555^2~226 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=623a71385312ee288d59e319b90922e6e6943766;p=platform%2Fkernel%2Flinux-rpi.git net/mlx4: Use bitmap_weight_and() Use bitmap_weight_and() instead of hand writing it. This saves a few LoC and is slightly faster, should it mater.
