The script I use to send patches adds --nogit --nogit-fallback
to copy only listed maintainers because people that send cleanup
patches don't generally like to get random patches.

That was a bad copy/paste of the script.
The actual script for RW is:
$ cat dev_attr_rw_backwards.perl
local $/;
while (<>) {
my $file = $_;
while ($file =~ m/\bDEVICE_ATTR\s*\(\s*(\w+)\s*,/g) {
my $var = $1;
if ($file =~ s/\bDEVICE_ATTR\s*\(\s*${var}\s*,\s*\(?(\s*S_IRUGO\s*\|\s*S_IWUSR|\s*S_IWUSR\s*\|\s*S_IRUGO\s*|\s*0644\s*)\)?\s*,\s*show_${var}\s*,\s*store_${var}\s*\)/DEVICE_ATTR_RW(${var})/g) {
$file =~ s/\bshow_${var}\b/${var}_show/g;
$file =~ s/\bstore_${var}\b/${var}_store/g;
}
}
print $file;
}
There are 3 different perl scripts for rw, ro, and wo.
and these scripts, because of function renaming and
possible reuse of the original function names by other
string concatenated macros, create some bad conversions
so they need some manual cleanups too.
Perhaps coccinelle could do a better job of it, but
likely string concatenation macro uses are going to
be hard to deal with in any case.
