The patch titled Subject: checkpatch: use proper way for show problematic line has been added to the -mm mm-nonmm-unstable branch. Its filename is checkpatch-use-proper-way-for-show-problematic-line.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/checkpatch-use-proper-way-for-show-problematic-line.patch This patch will later appear in the mm-nonmm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Thorsten Leemhuis <linux@xxxxxxxxxxxxx> Subject: checkpatch: use proper way for show problematic line Date: Fri, 20 Jan 2023 13:35:20 +0100 Instead of using an unnecessarily complicated approach to print a line that is warned about, use `$herecurr` instead, just like everywhere else in checkpatch. While at it, remove a superfluous space in one of the changed lines, too. In a unmodified line also remove a superfluous check for a space before a signed-off-by tag, to me consistent with the check at the start of the section. All three problems were found by Joe Perches during review of new code inspired by the code modified here.
