Hi,
This series aims to implement ethtool_puts() and send out a wave 1 of
conversions from ethtool_sprintf(). There's also a checkpatch patch
included to check for the cases listed below.
This was sparked from recent discussion here [1]
The conversions are used in cases where ethtool_sprintf() was being used
with just two arguments:
| ethtool_sprintf(&data, buffer[i].name);
or when it's used with format string: "%s"
| ethtool_sprintf(&data, "%s", buffer[i].name);
which both now become:
| ethtool_puts(&data, buffer[i].name);
The first case commonly triggers a -Wformat-security warning with Clang
due to potential problems with format flags present in the strings [3].
The second is just a bit weird with a plain-ol' "%s".
Note that I have some outstanding patches [2] (some picked up) that use
the second case of ethtool_sprintf(). I went with this approach to clean
up some strncpy() uses and avoid -Wformat-security warnings before
discussion about implementing ...puts() arose. I will probably let the
ones that have been picked up land but send new versions for others.
Wave 1 changes found with Cocci [4] and grep [5].

Use strscpy() to implement ethtool_puts().
Functionally the same as ethtool_sprintf() when it's used with two
arguments or with just "%s" format specifier.

This patch converts some basic cases of ethtool_sprintf() to
ethtool_puts().
The conversions are used in cases where ethtool_sprintf() was being used
with just two arguments:
| ethtool_sprintf(&data, buffer[i].name);
or when it's used with format string: "%s"
| ethtool_sprintf(&data, "%s", buffer[i].name);
which both now become:
| ethtool_puts(&data, buffer[i].name);
There are some outstanding patches [1] that I've sent using plain "%s"
with ethtool_sprintf() that should be ethtool_puts() now. Some have been
picked up as-is but I will send new versions for the others.

Add some warnings for using ethtool_sprintf() where a simple
ethtool_puts() would suffice.
The two cases are:
1) Use ethtool_sprintf() with just two arguments:
| ethtool_sprintf(&data, driver[i].name);
or
2) Use ethtool_sprintf() with a standalone "%s" fmt string:
| ethtool_sprintf(&data, "%s", driver[i].name);
The former may cause -Wformat-security warnings while the latter is just
not preferred. Both are safely in the category of warnings, not errors.

Why do you want this conversion?
Is it not possible for .name to contain a formatting field?

I'm rather doubt this is really desired or appropriate.

The case of using just two arguments to a ethtool_sprintf
call may cause -Wformat-security warnings. If it did indeed
have format specifiers then we would have more format
specifiers than arguments. Not ideal.
The second case of having a standalone "%s" isn't
necessarily bad or wrong. I used this exact approach to
replace some strncpy() usage in net drivers [1].
I'm working off guidance from Andrew Lunn [2] and Kees
who said it may be a good idea to tidy this up with a puts().
All in all, this patch doesn't do much but fix some warnings
and provide a more obvious interface. The number of
actual replacements are relatively low (around 20ish) so
I was hoping to sneak them in via this series.

Thanks Justin. From my perspective the series looks good, though I've
not spent very long on it. For the nfp parts:

I think cocci will do a better job at line folding if we adjust this
rule like I had to adjust the next rule: completely remove and re-add
the arguments:
- ethtool_sprintf(&BUF, VAR)
+ ethtool_puts(&BUF, VAR)
Then I think the handful of weird line wraps in the treewide patch will
go away.

This works for me for the ionic driver

Hi again Justin.
After I read patch 1/3 I don't object at all.
spatch/cocci will always be a better option than checkpatch
for conversions like this because it's a proper grammar parser
and checkpatch is a stupid little perl script.
If you resubmit this please:

o remove the whitespace before and after the parentheses
o use the same type "ETHTOOL_SPRINTF" or maybe "PREFER_ETHTOOL_PUTS"
for both warnings.
o Add a newline on the message output
o Add a --fix option
Something like:
