Subject: checkpatch: check for OpenOCD tree, not for kernel tree
X-Git-Url: https://git.gag.com/?p=fw%2Fopenocd;a=commitdiff_plain;h=20d4a58bd93aa17f8deb9ab6d310491f8fe9719b

checkpatch: check for OpenOCD tree, not for kernel tree

checkpatch.pl looks for Linux kernel specific paths and files
to check source tree. As openocd misses kernel files it ends
with this error message:

	Must be run from the top-level dir. of a kernel tree

This patch also renames 'kernel' -> 'openocd'
in source tree-related messages.

This is the old commit c5d89883165e ("checkpatch.pl: check for
openocd tree, not for kernel tree") re-applied.
Also remove the flag "--no-tree" from .checkpatch.conf, not
required anymore.
