+Subject: [PATCH] Revert "kinput: allocate enough space for null character."
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This reverts commit 531785dd746d64ef7f473a83ca73bb20e74b6fca.
+
+The above commit breaks Xephyr option parsing.  Andrzej writes:
+
+  Xephyr -retro -keybd evdev,,device=/dev/input/event2,xkbrules=evdev,xkbmodel=evdev,xkblayout=pl -mouse evdev,,device=/dev/input/event1 :3
+
+  results in:
+
+  <snip>
+  Pointer option key (device=) of value (/dev/input/event1) not assigned!
+  Kbd option key (device=) of value (/dev/input/event2) not assigned!
+  Kbd option key (xkbrules=) of value (evdev) not assigned!
+  Kbd option key (xkbmodel=) of value (evdev) not assigned!
+  Kbd option key (xkblayout=) of value (pl) not assigned!
+  <snip>
+
+  The effect of the patch is that the "key=value" pairs are parsed in such
+  a way that the key is added an "equals" sign to it and we end up with
+  keys like "device=" instead of "device". This in turn has effect on
+  KdParsePointerOptions and KdParseKbdOptions: the key does not match
+  any choice presented in the "switch" statement, and so "Pointer/Kbd
+  option key (...) of value (...) not assigned!" happens, making all
+  "key=value" options inaccessible to the user. Reverting the patch makes
+  them available again.
