If anyone has any objections, please let me know. ------------------ From: Roland Dreier commit d35212f3ca3bf4fb49d15e37f530c9931e2d2183 upstream. - instead of (PTR_ERR(file) < 0) just use IS_ERR(file) - return -EINVAL instead of EINVAL - all other error returns in target_scsi3_emulate_pr_out() use "goto out" -- get rid of the one remaining straight "return."
