Subject: [PATCH 02/46] perf probe: Use return of map__get() to make code more compact
Date:   Tue,  5 Jun 2018 14:49:46 -0300
Message-Id: <20180605175030.32549-3-acme@kernel.org>

From: Arnaldo Carvalho de Melo <acme@redhat.com>

The __get() idiom returns a reference count for the object passed, i.e.
all functions of this type return the object passed, so take advantage
of that to make the code more compact.
