kstrdup kernel primitive can be used to replace kmalloc followed by string copy. This was reported by coccinelle tool. Signed-off-by: Hari Prasath <gehariprasath@xxxxxxxxx> --- v1: Replace kmalloc followed by memcpy with kmemdup. Based on review comments from Alan Cox, this could better be done using kstrdup. v2: Replace kmalloc followed by memcpy by kstrdup in this case as it essentially is a string copy.Review comment recieved questioning the return value in case of error. Error value returned should be what the calling function is expecting. v3: Retain the original error value returned to the calling function if kstrdup() fails. --- .../staging/media/atomisp/pci/atomisp2/css2400/sh_css_firmware.c | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_firmware.c b/drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_firmware.c index 34cc56f..5d231ee 100644 --- a/drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_firmware.c +++ b/drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_firmware.c @@ -144,14 +144,10 @@ sh_css_load_blob_info(const char *fw, const struct ia_css_fw_info *bi, struct ia ) { char *namebuffer; - int namelength = (int)strlen(name); - namebuffer = (char *) kmalloc(namelength + 1, GFP_KERNEL); - if (namebuffer == NULL) + namebuffer = kstrdup(name, GFP_KERNEL); + if (!namebuffer) return IA_CSS_ERR_CANNOT_ALLOCATE_MEMORY; - - memcpy(namebuffer, name, namelength + 1); - bd->name = fw_minibuffer[index].name = namebuffer; } else { bd->name = name; -- 2.10.0.GIT _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
