6.12-stable review patch. If anyone has any objections, please let me know.

From: Arnd Bergmann arnd@arndb.de
commit d0bbe332669c5db32c8c92bc967f8e7f8d460ddf upstream.
The alternative path leads to a build error after a recent change:
sound/pci/hda/patch_realtek.c: In function 'alc233_fixup_lenovo_low_en_micmute_led': include/linux/stddef.h:9:14: error: called object is not a function or function pointer 9 | #define NULL ((void *)0) | ^ sound/pci/hda/patch_realtek.c:5041:49: note: in expansion of macro 'NULL' 5041 | #define alc233_fixup_lenovo_line2_mic_hotkey NULL | ^~~~ sound/pci/hda/patch_realtek.c:5063:9: note: in expansion of macro 'alc233_fixup_lenovo_line2_mic_hotkey' 5063 | alc233_fixup_lenovo_line2_mic_hotkey(codec, fix, action);
Using IS_REACHABLE() is somewhat questionable here anyway since it leads to the input code not working when the HDA driver is builtin but input is in a loadable module. Replace this with a hard compile-time dependency on CONFIG_INPUT. In practice this won't chance much other than solve the compiler error because it is rare to require sound output but no input support.
