Subject: [PATCH] ASoC: mt6359: fix tests for platform_get_irq() failure
Date: Thu, 11 Aug 2022 14:01:26 +0300 [thread overview]
Message-ID: <YvThhr86N3qQM2EO@kili> (raw)
The platform_get_irq() returns negative error codes. It can't actually
return zero, but if it did that should be treated as success.
Fixes: eef07b9e0925 ("ASoC: mediatek: mt6359: add MT6359 accdet jack driver")
