From e98631d83c84adfee9d33f04808a6e0eb2fa0345 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Tue, 22 Sep 2015 02:39:36 +0200 Subject: [PATCH] staging: dgap: fix returned errno code in dgap_parsefile() The driver is using -1 instead of the -ENOMEM defined macro to specify that a buffer allocation failed. Since the error number is propagated, the caller will get a -EPERM which is the wrong error condition. Also, the smatch tool complains with the following warning: dgap_parsefile() warn: returning -1 instead of -ENOMEM is sloppy Signed-off-by: Javier Martinez Canillas Signed-off-by: Greg Kroah-Hartman --- drivers/staging/dgap/dgap.c | 32 ++++++++++++++++---------------- 1 file changed, 16 insertions(+), 16 deletions(-) diff --git a/drivers/staging/dgap/dgap.c b/drivers/staging/dgap/dgap.c index 303d9702..e17bde7 100644 --- a/drivers/staging/dgap/dgap.c +++ b/drivers/staging/dgap/dgap.c @@ -642,7 +642,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; @@ -861,7 +861,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = TNODE; @@ -883,7 +883,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = CUNODE; @@ -914,7 +914,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = LNODE; @@ -933,7 +933,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = CNODE; @@ -975,7 +975,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = MNODE; @@ -1054,7 +1054,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = PNODE; @@ -1076,7 +1076,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = JNODE; @@ -1098,7 +1098,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = ANODE; @@ -1120,7 +1120,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = INTRNODE; @@ -1141,7 +1141,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = TSNODE; @@ -1163,7 +1163,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = CSNODE; @@ -1185,7 +1185,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = BSNODE; @@ -1207,7 +1207,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = USNODE; @@ -1229,7 +1229,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = FSNODE; @@ -1251,7 +1251,7 @@ static int dgap_parsefile(char **in) p->next = kzalloc(sizeof(struct cnode), GFP_KERNEL); if (!p->next) - return -1; + return -ENOMEM; p = p->next; p->type = VSNODE; -- 2.7.4
