The script checkpatch available in new Linux kernel offers an
experimental feature for automatically fix the code in place.
While still experimental, the feature works quite well for simple
fixes, like spacing.
This patch has been created automatically with the script under
review for inclusion in OpenOCD, using the command:
find tcl/ -type f -exec ./tools/scripts/checkpatch.pl \
-q --types TRAILING_WHITESPACE --fix-inplace -f {} \;
The patch only changes amount and position of whitespace, thus
the following commands show empty diff
git diff -w
git log -w -p
git log -w --stat
