[PATCH] objtool: Rename elf_open() to prevent conflict with libelf from elftoolchain

[Josh Poimboeuf]

From: Michael Forney <mfor...@mforney.org>

The elftoolchain version of libelf has a function named elf_open().

The function name isn't quite accurate anyway, since it also reads all
the ELF data.  Rename it to elf_read(), which is more accurate.

[ jpoimboe: rename to elf_read(); write commit description ]
