Signed-off-by: David E. Box Reviewed-by: Ilpo Järvinen --- V6 - No change V5 - Assign no_free_ptr(res) to resource member. This fixes __must_check_fn warning. - Remove unsed ret variable. V4 - Do no_free_ptr() before and in call to intel_vsec_add_aux(). - Add resource cleanup in this patch. V3 - New patch. drivers/platform/x86/intel/vsec.c | 18 +++++++++++------- 1 file changed, 11 insertions(+), 7 deletions(-) diff --git a/drivers/platform/x86/intel/vsec.c b/drivers/platform/x86/intel/vsec.c index ba352af65dde..27e8698ebe5e 100644 --- a/drivers/platform/x86/intel/vsec.c +++ b/drivers/platform/x86/intel/vsec.c @@ -15,6 +15,7 @@ #include #include +#include #include #include #include @@ -147,8 +148,9 @@ EXPORT_SYMBOL_NS_GPL(intel_vsec_add_aux, INTEL_VSEC); static int intel_vsec_add_dev(struct pci_dev *pdev, struct intel_vsec_header *header, struct intel_vsec_platform_info *info) { - struct intel_vsec_device *intel_vsec_dev; - struct resource *res, *tmp; + struct intel_vsec_device __free(kfree) *intel_vsec_dev = NULL; + struct resource __free(kfree) *res = NULL; + struct resource *tmp; unsigned long quirks = info->quirks; int i; @@ -170,10 +172,8 @@ static int intel_vsec_add_dev(struct pci_dev *pdev, struct intel_vsec_header *he return -ENOMEM; res = kcalloc(header->num_entries, sizeof(*res), GFP_KERNEL); - if (!res) { - kfree(intel_vsec_dev); + if (!res) return -ENOMEM; - } if (quirks & VSEC_QUIRK_TABLE_SHIFT) header->offset >>= TABLE_OFFSET_SHIFT; @@ -191,7 +191,7 @@ static int intel_vsec_add_dev(struct pci_dev *pdev, struct intel_vsec_header *he } intel_vsec_dev->pcidev = pdev; - intel_vsec_dev->resource = res; + intel_vsec_dev->resource = no_free_ptr(res); intel_vsec_dev->num_resources = header->num_entries; intel_vsec_dev->quirks = info->quirks; @@ -200,7 +200,11 @@ static int intel_vsec_add_dev(struct pci_dev *pdev, struct intel_vsec_header *he else intel_vsec_dev->ida = &intel_vsec_ida; - return intel_vsec_add_aux(pdev, NULL, intel_vsec_dev, + /* + * Pass the ownership of intel_vsec_dev and resource within it to + * intel_vsec_add_aux() + */ + return intel_vsec_add_aux(pdev, NULL, no_free_ptr(intel_vsec_dev), intel_vsec_name(header->id)); }
