From 2b542a13a94f310e718f2ed57b0f712b9ddbbbef Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Wed, 23 Dec 2009 20:34:29 +0000 Subject: [PATCH] ARM: S3C: Fix NAND device registration by s3c_nand_set_platdata(). Fix two bugs in s3c_nand_set_platdata() where thet device's platform data was not set, and the wrong error check was being performed on the return of s3c_nand_copy_set(). Fixes the following OOPS: Unable to handle kernel NULL pointer dereference at virtual address 00000004 PC is at s3c24xx_nand_probe+0x234/0x594 Signed-off-by: Ben Dooks --- arch/arm/plat-s3c/dev-nand.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/arch/arm/plat-s3c/dev-nand.c b/arch/arm/plat-s3c/dev-nand.c index e771e77dcd5..84808ccda70 100644 --- a/arch/arm/plat-s3c/dev-nand.c +++ b/arch/arm/plat-s3c/dev-nand.c @@ -114,7 +114,7 @@ void __init s3c_nand_set_platdata(struct s3c2410_platform_nand *nand) for (i = 0; i < npd->nr_sets; i++) { ret = s3c_nand_copy_set(to); - if (!ret) { + if (ret) { printk(KERN_ERR "%s: failed to copy set %d\n", __func__, i); return; @@ -122,6 +122,8 @@ void __init s3c_nand_set_platdata(struct s3c2410_platform_nand *nand) to++; } } + + s3c_device_nand.dev.platform_data = npd; } EXPORT_SYMBOL_GPL(s3c_nand_set_platdata);
