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: //<smpl> @@ 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) //</smpl> Acked-by: John Youn <johnyoun@synopsys.com> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: Felipe Balbi <balbi@kernel.org>
