From: Julia Lawall <redacted> Use WARN rather than printk followed by WARN_ON(1), for conciseness. If (count) is also merged into WARN, for further conciseness. A simplified version of the semantic patch that makes part of this transformation is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression list es; @@ -printk( +WARN(1, es); -WARN_ON(1); // </smpl> Signed-off-by: Julia Lawall <redacted> --- drivers/scsi/gdth.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-)
