Subject: [PATCH 6.0 360/862] ASoC: mt6359: fix tests for platform_get_irq() failure

From: Dan Carpenter <dan.carpenter@...cle.com>

[ Upstream commit 51eea3a6fb4d39c2cc71824e6eee5949d7ae4d1c ]

The platform_get_irq() returns negative error codes.  It can't actually
return zero, but if it did that should be treated as success.
