From 9bbe91a1ea4cae20ff9f8f175c92e1e49b4296d9 Mon Sep 17 00:00:00 2001 From: Amitoj Kaur Chawla Date: Mon, 22 Feb 2016 13:40:32 +0530 Subject: [PATCH] usb: dwc2: Use kmem_cache_free() Here, free memory is allocated using kmem_cache_zalloc. So, use kmem_cache_free instead of kfree. This is done using Coccinelle and semantic patch used is as follows: // @@ expression x,E,c; @@ x = \(kmem_cache_alloc\|kmem_cache_zalloc\|kmem_cache_alloc_node\)(c,...) ... when != x = E when != &x ?-kfree(x) +kmem_cache_free(c,x) // Acked-by: John Youn Signed-off-by: Amitoj Kaur Chawla Signed-off-by: Felipe Balbi --- drivers/usb/dwc2/hcd_ddma.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/usb/dwc2/hcd_ddma.c b/drivers/usb/dwc2/hcd_ddma.c index 2ff517a..27350d0 100644 --- a/drivers/usb/dwc2/hcd_ddma.c +++ b/drivers/usb/dwc2/hcd_ddma.c @@ -111,7 +111,7 @@ static int dwc2_desc_list_alloc(struct dwc2_hsotg *hsotg, struct dwc2_qh *qh, dma_unmap_single(hsotg->dev, qh->desc_list_dma, qh->desc_list_sz, DMA_FROM_DEVICE); - kfree(qh->desc_list); + kmem_cache_free(desc_cache, qh->desc_list); qh->desc_list = NULL; return -ENOMEM; } -- 2.7.4
