From: Leonard Crestez <leonard.crestez@xxxxxxx>
Subject: scripts/gdb: lx-dmesg: cast log_buf to void* for addr fetch

In some cases it is possible for the str() conversion here to throw
encoding errors because log_buf might not point to valid ascii.  For
example:

(gdb) python print str(gdb.parse_and_eval("log_buf"))
Traceback (most recent call last):
  File "<string>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\u0303' in
	position 24: ordinal not in range(128)

Avoid this by explicitly casting to (void *) inside the gdb expression.
