Subject: [PATCH 08/54] net: ethernet: replace bitmap_weight with bitmap_empty for intel
Date:   Sun, 23 Jan 2022 10:38:39 -0800

The ice_vf_has_no_qs_ena() calls bitmap_weight() to check if any bit
of a given bitmap is set. It's better to use bitmap_empty() in that
case because bitmap_empty() stops traversing the bitmap as soon as it
finds first set bit, while bitmap_weight() counts all bits
unconditionally.
