Subject: [PATCH] mesa: fix _mesa_draw_nonzero_divisor_bits to return nonzero
 divisors
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The bitmask is _EffEnabledNonZeroDivisor, so no need to invert it before
returning.

Fixes: fd6636ebc06d (st/mesa: simplify determination whether a draw needs min/max index)
