Subject: [PATCH v2 1/5] i2c: hix5hd2: fix IRQ check
Date: Sun, 4 Jul 2021 17:35:54 +0300	[thread overview]
Message-ID: <f6ab965b-2ac1-ee30-358b-a4ca45708f33@omp.ru> (raw)
In-Reply-To: <3712e871-bf2f-32c5-f9c2-2968c42087f8@omp.ru>

Iff platform_get_irq() returns 0, the driver's probe() method will return 0
early (as if the method's call was successful).  Let's consider IRQ0 valid
for simplicity -- devm_request_irq() can always override that decision...
