From: Julia Lawall <[email protected]> This code elsewhere returns a negative constant to an indicate an error, while IS_ERR returns the result of a >= operation.
The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x; @@ if (...) { ... - return IS_ERR(x); + return PTR_ERR(x); } // </smpl> Signed-off-by: Julia Lawall <[email protected]> Acked-by: David Brown <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> --- drivers/staging/msm/lcdc.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/staging/msm/lcdc.c b/drivers/staging/msm/lcdc.c index 735280a..8183394 100644 --- a/drivers/staging/msm/lcdc.c +++ b/drivers/staging/msm/lcdc.c @@ -224,12 +224,12 @@ static int __init lcdc_driver_init(void) mdp_lcdc_pclk_clk = clk_get(NULL, "mdp_lcdc_pclk_clk"); if (IS_ERR(mdp_lcdc_pclk_clk)) { printk(KERN_ERR "error: can't get mdp_lcdc_pclk_clk!\n"); - return IS_ERR(mdp_lcdc_pclk_clk); + return PTR_ERR(mdp_lcdc_pclk_clk); } mdp_lcdc_pad_pclk_clk = clk_get(NULL, "mdp_lcdc_pad_pclk_clk"); if (IS_ERR(mdp_lcdc_pad_pclk_clk)) { printk(KERN_ERR "error: can't get mdp_lcdc_pad_pclk_clk!\n"); - return IS_ERR(mdp_lcdc_pad_pclk_clk); + return PTR_ERR(mdp_lcdc_pad_pclk_clk); } // pm_qos_add_requirement(PM_QOS_SYSTEM_BUS_FREQ , "lcdc", // PM_QOS_DEFAULT_VALUE); -- 1.7.4.1 _______________________________________________ devel mailing list [email protected] http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
