+Subject: [PATCH] Use dynamic structures instead of predefined ones
+
+ * The file /proc/acpi/wakeup can have much more than 25 entries.
+   In my computer (Dell E6420) I have 27 entries.
+   So instead of using an array of [x] entries better use dynamic
+   vectors and push the new entries when a new line from the file
+   is read.
+
+ * The name of the device is not ever 4 characters. For example I
+   have a device called "LID" which is 3 characters long.
+   Instead of using a fixed size for the device we split the line
+   on the first tab (\t) and use the first part.
