Conditionally calling kfree()/vfree() can be replaced by a call to kvfree() which handles both kmalloced memory and vmalloced memory. Consequently removed an unnecessary comment. The Coccinelle semantic patch used to make the change is as follows: //<smpl> @@ expression a; @@ - if(...) { vfree(a); } - else { kfree(a); } + kvfree(a); @@ expression a; @@ - if(...) { kfree(a); } - else { vfree(a); } + kvfree(a); // </smpl> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> --- drivers/staging/media/atomisp/pci/atomisp2/atomisp_cmd.c | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-)
