4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lukas Bulwahn <lukas.bulwahn@gmail.com>
commit e7e83dd3ff1dd2f9e60213f6eedc7e5b08192062 upstream.
Fix the following Clang enum conversion warning:
arch/x86/decode.c:141:20: error: implicit conversion from enumeration type 'enum op_src_type' to different enumeration type 'enum op_dest_type' [-Werror,-Wenum-conversion]
op->dest.type = OP_SRC_REG; ~ ^~~~~~~~~~
It just happened to work before because OP_SRC_REG and OP_DEST_REG have the same value.
