Re: [PATCH 3/3] Fix discards 'const' qualifier from pointer target type warnings

The event_note_list pointer is reassigned and its members are also reassigned. It should not be declared with the const qualifier. The ptr variable, in unescape(), cannot be used to modify a string since it is initialized to the const char *buf input parameter. Rather than modifying buf, we can use ptr as a placeholder and use strndup() to allocate str. Later in the function a new, non-const pointer is used to modify str. These changes allow unescape() to still take a const char * as its input parameter. Signed-off-by: Tyler Hicks <tyhicks(a)canonical.com&gt;
