Re: [PATCH 5/8] drivers/staging/line6/driver.h: Changed printk(KERN_ERR, .. to pr_err Changed printk(KERN_ERR, ...) call to pr_err() call in MISSING_CASE macro
MISSING_CASE is a horrible macro. Just replace all the code which uses MISSING_CASE. Or better yet, delete all the uses. (I haven't looked through them).
