Thanks I missed that. But moving the debug function in i8042_check_quirks would make the output x86 exclusive, while the
quirks in general are not (on non x86 they must be set via command line but still have effects on the code if i see that
correctly)

As an alternative i would suggest putting defines in the pr_debug call. Otherwise it might not be immediately that the
#define i8042_nopnp 0 is there specifically for this one statement only.
pr_debug("Active quirks (empty means none):%s%s%s%s%s%s%s%s%s%s%s%s%s\n",
i8042_nokbd ? " nokbd" : "",
i8042_noaux ? " noaux" : "",
i8042_nomux ? " nomux" : "",
i8042_unlock ? " unlock" : "",
i8042_probe_defer ? "probe_defer" : "",
i8042_reset == I8042_RESET_DEFAULT ?
"" : i8042_reset == I8042_RESET_ALWAYS ?
" reset_always" : " reset_never",
i8042_direct ? " direct" : "",
i8042_dumbkbd ? " dumbkbd" : "",
i8042_noloop ? " noloop" : "",
i8042_notimeout ? " notimeout" : "",
i8042_kbdreset ? " kbdreset" : "",
#ifdef CONFIG_X86
i8042_dritek ? " dritek" : "",
#else
"",
#endif
#ifdef CONFIG_PNP
i8042_nopnp ? " nopnp" : "");
#else
"");
#endif
As a side effect: like this the code snipped also stays completely position independed.
