Subject: [PATCH -next] iio: adc: fix the return value handle for platform_get_irq()
Date: Thu, 27 Jul 2023 21:16:07 +0800	[thread overview]
Message-ID: <20230727131607.2897937-1-ruanjinjie@huawei.com> (raw)

There is no possible for platform_get_irq() to return 0
and the return value of platform_get_irq() is more sensible
to show the error reason.
