Pedro Alves - Jan. 23, 2019, 3:21 p.m.
From: Tom Tromey <tom@tromey.com>

In v3: remove the "have BKPT_CHAIN already discarded" comment too.

The remaining null cleanup in breakpoint.c does not seem to protect
anything, so remove it.

gdb/ChangeLog:
yyyy-mm-dd  Tom Tromey  <tom@tromey.com>
	    Pedro Alves  <palves@redhat.com>

	* breakpoint.c (create_breakpoint): Remove cleanup.
