Subject: [PATCH 03/40] perf trace: Add missing ' = ' in the default formatting of syscall returns

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

We lost it recently, put it back.

Before:

  789.499 ( 0.001 ms): libvirtd/1175 lseek(fd: 22, whence: CUR) 4328

After:

  789.499 ( 0.001 ms): libvirtd/1175 lseek(fd: 22, whence: CUR) = 4328
