Subject: [PATCH] spi_imx.c: correct the test on platform_get_irq() return value
Date: Fri, 7 Jan 2011 15:26:01 +0100 [thread overview]
Message-ID: <1294410361-9092-1-git-send-email-richard.genoud@gmail.com> (raw)
In-Reply-To: <AANLkTimpTUz_Fizef09urPBR8vP80KU-5yApjzGWFwc0@mail.gmail.com>
The test "if (spi_imx->irq <= 0)" is not testing the IRQ value, but the return value of platform_get_irq().
As platform_get_irq() can return an error (-ENXIO) or the IRQ value it found, the test should be "if (spi_imx->irq < 0)"
