[alsa-devel] [PATCH 2/3] asoc: (cosmetic) simplify a condition

[Guennadi Liakhovetski]

From: Guennadi Liakhovetski <guennadi.liakhovetski at linux.intel.com>

Double negation is often used in the kernel to avoid explicit comparison
to 0. However an "if (!!a == !!b)" test can be trivially reduced to "if
(!a == !b)".
