Subject: [PATCH -next] spi: fsl-spi: Do not check 0 for platform_get_irq()
Date: Thu, 3 Aug 2023 16:39:44 +0800	[thread overview]
Message-ID: <20230803083944.21501-1-wangzhu9@huawei.com> (raw)

Since platform_get_irq() never returned zero, so it need not to check
whether it returned zero, and we use the return error code of
platform_get_irq() to replace the current return error code, for that
platform_get_irq() may return -EINVAL or -ENXIO.
