Subject: [PATCH] Input: hp_sdc_rtc - mark an unused function as __maybe_unused
Git-commit: 586dc36226dd748b197eea8642c087cae611129b
Patch-mainline: v6.4-rc1
References: git-fixes

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)
      |            ^~~~~~~~~~~~~~~~~~~~
