Multiline statements with invalid %p<foo> uses produce multiple
warnings.  Fix that.

e.g.:

$ cat t_block.c
void foo(void)
{
	MY_DEBUG(drv->foo,
		 "%pk",
		 foo->boo);
}

$ ./scripts/checkpatch.pl -f t_block.c

total: 0 errors, 3 warnings, 6 lines checked

NOTE: For some of the reported defects, checkpatch may be able to
      mechanically convert to the typical style using --fix or --fix-inplace.

t_block.c has style problems, please review.

NOTE: If any of the errors are false positives, please report
      them to the maintainer, see CHECKPATCH in MAINTAINERS.

Note that the LZ4 signature is different than that of modern LZ4 as we
use the "legacy" format which suffers from some downsides like inability
to disable compression.

The comment is the same as in the top-level Makefile.

Also, the comments contain typos:
  - the .PHONY variable  ->  the PHONY variable
  - se we can ...        ->  so we can ...

Instead of fixing the typos, just remove the duplicated comments.

The comment line for addtree says "skip if -I has no parameter".

What it actually does is "drop if -I has no parameter".  For example,
if you have the compiler flag '-I foo' (a space between), it will be
converted to 'foo'.  This completely changes the meaning.

What we want is, "do nothing" for -I without parameter so that
'-I foo' is kept as-is.

Each symbol has a property of type P_SYMBOL since commit

Handle those properties in print_symbol().

Further, place a pointer to print_symbol() in the comment above the
