Hello Mario Limonciello,
The patch e8129a076a50: "pinctrl: amd: Use unicode for debugfs
output" from Jul 22, 2022, leads to the following Smatch static
checker warning:

I didn't add this Smatch check and I don't know the rules for this so
when someone adds something that basically looks sane, I don't report
it.
All of those are expected to me. If there are rules against this type
of change then we should (unfortunately) revert that patch and the
follow on patch that fixed an unused variable.
drivers/pinctrl/pinctrl-amd.c
247 seq_printf(s, "GPIO bank%d\n", bank);
248 for (; i < pin_num; i++) {
249 seq_printf(s, "📌%d\t", i);

In Gnome this looks like a thumbtack.
Right, it's replacing "Pin".
...
279
280 if (pin_reg & BIT(INTERRUPT_MASK_OFF))
281 interrupt_mask = "-";
282 else
283 interrupt_mask = "+";
284 seq_printf(s, "int %s (🎭 %s)| active-%s| %s-🔫| ",
Gnome emojis seem difficult to read. Theatre masks and a water gun?
"Mask" and "Trigger"
285 interrupt_enable,
286 interrupt_mask,
287 active_level,
--> 288 level_trig);
289
290 if (pin_reg & BIT(WAKE_CNTRL_OFF_S0I3))
291 wake_cntrl0 = "+";
292 else
293 wake_cntrl0 = "∅";
294 seq_printf(s, "S0i3 🌅 %s| ", wake_cntrl0);
Sunrise emoji?
"S0i3 Wakeup"
...
369 snprintf(debounce_value, sizeof(debounce_value), "%u", time * unit);
370 seq_printf(s, "debounce %s (⏰ %sus)| ", debounce_enable, debounce_value);
Alarm clock.
"Debounce time"
371 seq_printf(s, " 0x%x\n", pin_reg);
372 }
373 }
374 }

Yeah all of those emoji are the ones I intended. Details above. The
point of this patch was to shrink the length of the line in debugfs
output into something more manageable that it didn't need to be imported
into a CSV processor to look at the data. It can be used with something
like "less" now.
If you (or anyone else) has a better proposal for any of those symbols
I'm happy to make a change. My goal remains to keep the lines ultra
short though.
