From 51e911e27690aecea01d4fe9cb22d38bdd0748ac Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 6 Jan 2009 14:41:45 -0800 Subject: drivers/spi: move a dereference below a NULL test In each case, if the NULL test is necessary, then the dereference should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @@ type T; expression E; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E when != i if (E == NULL) S + i = E->fld; // Signed-off-by: Julia Lawall Acked-by: David Brownell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/spi/pxa2xx_spi.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'drivers/spi') diff --git a/drivers/spi/pxa2xx_spi.c b/drivers/spi/pxa2xx_spi.c index 6104f46..d0fc4ca 100644 --- a/drivers/spi/pxa2xx_spi.c +++ b/drivers/spi/pxa2xx_spi.c @@ -1561,11 +1561,12 @@ out_error_master_alloc: static int pxa2xx_spi_remove(struct platform_device *pdev) { struct driver_data *drv_data = platform_get_drvdata(pdev); - struct ssp_device *ssp = drv_data->ssp; + struct ssp_device *ssp; int status = 0; if (!drv_data) return 0; + ssp = drv_data->ssp; /* Remove the queue */ status = destroy_queue(drv_data); -- cgit v1.1
