From 4f5177458ba97734149897c5d4d44f85b8fe0348 Mon Sep 17 00:00:00 2001 From: Rajeshwar R Shinde Date: Mon, 7 Aug 2023 20:19:42 +0530 Subject: spi: spi-mpc52xx-psc: Fix an unsigned comparison that can never be negative In struct mpc52xx_psc_spi, the variable 'irq' is declared as an unsigned int. The comparison of variable 'irq' with signed int operand is incorrect. Also, the return value from the call to platform_get_irq(pdev,0) is int and it is assigned to an unsigned int variable 'irq', thus redeclaring the type of variable 'irq' to signed int. This fixes warning such as: drivers/spi/spi-mpc52xx-psc.c:332:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0 Signed-off-by: Rajeshwar R Shinde Link: https://lore.kernel.org/r/20230807144942.30317-2-coolrrsh@gmail.com Signed-off-by: Mark Brown --- drivers/spi/spi-mpc52xx-psc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/spi/spi-mpc52xx-psc.c') diff --git a/drivers/spi/spi-mpc52xx-psc.c b/drivers/spi/spi-mpc52xx-psc.c index 9a1a080fb688..795c08594a4d 100644 --- a/drivers/spi/spi-mpc52xx-psc.c +++ b/drivers/spi/spi-mpc52xx-psc.c @@ -29,7 +29,7 @@ struct mpc52xx_psc_spi { /* driver internal data */ struct mpc52xx_psc __iomem *psc; struct mpc52xx_psc_fifo __iomem *fifo; - unsigned int irq; + int irq; u8 bits_per_word; struct completion done; -- cgit v1.2.3
