[PATCH] input/misc: hp_sdc_rtc: mark an unused function as __maybe_unused

[PATCH] input/misc: hp_sdc_rtc: mark an unused function as __maybe_unused

[Randy Dunlap]

When CONFIG_PROC_FS is not set, one procfs-related function is not
used, causing a build error or warning.
Mark this function as __maybe_unused to quieten the build.

../drivers/input/misc/hp_sdc_rtc.c:268:12: warning: 'hp_sdc_rtc_proc_show' defined but not used [-Wunused-function]
  268 | static int hp_sdc_rtc_proc_show(struct seq_file *m, void *v)
      |            ^~~~~~~~~~~~~~~~~~~~

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
