[bug report] pinctrl: amd: Use unicode for debugfs output

[Dan Carpenter <dan.carpenter@oracle.com>]

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:

drivers/pinctrl/pinctrl-amd.c:249 amd_gpio_dbg_show() warn: format string contains non-ascii character '\x8c'
drivers/pinctrl/pinctrl-amd.c:288 amd_gpio_dbg_show() warn: format string contains non-ascii character '\x8e'
drivers/pinctrl/pinctrl-amd.c:294 amd_gpio_dbg_show() warn: format string contains non-ascii character '\x85'
drivers/pinctrl/pinctrl-amd.c:300 amd_gpio_dbg_show() warn: format string contains non-ascii character '\x85'
drivers/pinctrl/pinctrl-amd.c:306 amd_gpio_dbg_show() warn: format string contains non-ascii character '\x85'
drivers/pinctrl/pinctrl-amd.c:320 amd_gpio_dbg_show() warn: format string contains non-ascii character '\x86'
drivers/pinctrl/pinctrl-amd.c:326 amd_gpio_dbg_show() warn: format string contains non-ascii character '\x86'
drivers/pinctrl/pinctrl-amd.c:326 amd_gpio_dbg_show() warn: format string contains non-ascii character '\xe2'
drivers/pinctrl/pinctrl-amd.c:370 amd_gpio_dbg_show() warn: format string contains non-ascii character '\xe2'

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.

    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.

    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?

    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?

    369                         snprintf(debounce_value, sizeof(debounce_value), "%u", time * unit);
    370                         seq_printf(s, "debounce %s (⏰ %sus)| ", debounce_enable, debounce_value);

Alarm clock.

    371                         seq_printf(s, " 0x%x\n", pin_reg);
    372                 }
    373         }
    374 }
