Currently running checkpatch on a directory with a cover-letter.patch
file reports the following error:
-----------------------------------------
patches/smp-v2/v2-0000-cover-letter.patch
-----------------------------------------
ERROR: Does not appear to be a unified-diff format patch
The logic to suppress the unified-diff check for cover letters is there
but is checking $file instead of $filename. Fix the variable to use the
correct one.

Unlike all other types, LONG_LINE, LONG_LINE_COMMENT and LONG_LINE_STRING
are passed to WARN() through a variable. This causes the parser in
list_types() to miss them and consequently they are not present in the
output of --list-types.
Additionally, types TYPO_SPELLING, FSF_MAILING_ADDRESS and AVOID_BUG are
passed with a variable level, causing the parser to miss them too.
So modify the regex to also catch these special cases.

The variable name "$msg_type" is sometimes used to set the message type,
and sometimes used to set the message level. This works but is kind of
confusing. Use "$msg_level" in the latter case instead, to make the code

The boolean --color argument did not offer the ability to force
colourized output even if stdout is not a terminal. Change the format
of the argument to the familiar --color[=WHEN] construct as seen in
common Linux utilities such as git, ls and dmesg, which allows the user
to specify whether to colourize output "always", "never", or "auto" when
the output is a terminal. The default is "auto".
The old command-line uses of --color and --no-color are unchanged.

90% of the usage of device node's full_name is printing it out in a
kernel message. However, storing the full path for every node is
wasteful and redundant. With a custom format specifier, we can generate
the full path at run-time and eventually remove the full path from every
node.
For instance typical use is:
pr_info("Frobbing node %s\n", node->full_name);
Which can be written now as:
pr_info("Frobbing node %pOF\n", node);
'%pO' is the base specifier to represent kobjects with '%pOF'
representing struct device_node. Currently, struct device_node is the
only supported type of kobject.
More fine-grained control of formatting includes printing the name,
flags, path-spec name and others, explained in the documentation entry.

There was a time when the expedited grace-period primitives
(synchronize_rcu_expedited(), synchronize_rcu_bh_expedited(), and
synchronize_sched_expedited()) used rather antisocial kernel
facilities like try_stop_cpus(). However, they have since been
housebroken to use only single-CPU IPIs, and typically cause less
disturbance than a scheduling-clock interrupt. Furthermore, this
disturbance can be eliminated entirely using NO_HZ_FULL on the
one hand or the rcupdate.rcu_normal boot parameter on the other.
This commit therefore removes checkpatch's complaints about use
of the expedited RCU primitives.

The default NetBSD package manager is pkgsrc and it installs Perl

The default prefix for binary prebuilt packages is /usr/pkg, and the
Perl executable lands in /usr/pkg/bin/perl.
This change switches "/usr/bin/perl" to "/usr/bin/env perl" as it's
the most portable solution that should work for almost everybody.
Perl's executable is detected automatically.
This change switches -w option passed to the executable with more

When using checkpatch on out-of-tree code, it may occur that some
project-specific types are used, which will cause spurious warnings.
Add the --typedefsfile option as a way to extend the known types and
deal with this issue.
This was developed for OP-TEE [1]. We run a Travis job on all pull
requests [2], and checkpatch is part of that. The typical false warning
we get on a regular basis is with some pointers to functions returning
TEE_Result [3], which is a typedef from the GlobalPlatform APIs. We
consider it is acceptable to use GP types in the OP-TEE core
implementation, that's why this patch would be helpful for us.

vsnprintf extension %Z<foo> is non-standard C. Suggest the use of %z
instead.
Miscellanea:
- Correct the misuse of type string PRINTF_0xDECIMAL type strings are
supposed to be uppercase only. Fix this and add tr/[a-z]/[A-Z] to the
type check in case I forget this again sometime in the future.
- Improve the mechanism to find these defects so all 3 current checks
are done on the format string

Lines containing "} else {" should not be detected as unbalanced braces.
But the second check can be reduced to ".+else\s*{" and it therefore
never checked if the beginning of a line contains any other character
(like the relevant "}"). This check would also return true for "} else
{" and create warnings like
CHECK: Unbalanced braces around else statement
#391: FILE: ./net/batman-adv/tvlv.c:391:
+ } else {
The check can be changed to check the whole line for the missing "}" to
avoid this false positive.
Fixes: 0d1532456c26 ("checkpatch: notice unbalanced else braces in a patch")

It's another busy cycle for the docs tree, as the sphinx conversion
continues. Highlights include:
- Further work on PDF output, which remains a bit of a pain but should be
more solid now.
- Five more DocBook template files converted to Sphinx. Only 27 to go...
Lots of plain-text files have also been converted and integrated.
- Images in binary formats have been replaced with more source-friendly
versions.
- Various bits of organizational work, including the renaming of various
files discussed at the kernel summit.
- New documentation for the device_link mechanism.
...and, of course, lots of typo fixes and small updates.

ERROR: Does not appear to be a unified-diff format patch
total: 1 errors, 1 warnings, 0 lines checked
NOTE: For some of the reported defects, checkpatch may be able to

lpc-dt/0006-mfd-dt-Move-syscon-bindings-to-syscon-subdirectory.patch has style problems, please review.
NOTE: If any of the errors are false positives, please report

The patch in question was all renames with no edits, giving 100%

member = <foo>;
is generally hard to follow.

exempt them from long line checks and various .[ch] file type tests.
And as well, only scan absolute paths in the commit log, not in the
