Re: [PATCH v6] checkpatches.sh: Add checks for ABI symbol addition

[Thomas Monjalon <thomas@monjalon.net>]

Hi Neil,

Sorry, this patch has been forgotten during the whole release cycle.

I see an issue about the dependency on filterdiff.
Is there a way to avoid it?

I have some minor comments below.

This new blank line is probably a leftover.

It is preferred to use $() construct to be consistent in the file.

No need to use cat here.

All calls to DPDK_CHECKPATCH_PATH can be moved to one call after the "fi".
Just need to set TPMINPUT=$1 in first case (and not remove TPMINPUT
in this case).

For consistency, the style in this file is:
	if [ $? -ne 0 ] ; then

> +		printf '%s\n' "$report" | sed -n '1,/^total:.*lines checked$/p'

Same as above, it can be simplified by only one line for all cases.
