[PATCH 4.4 05/74] x86/microcode/intel: Fix BDW late-loading revision check

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <ben.hutchings@xxxxxxxxxxxxxxx>

The backport of commit b94b73733171 ("x86/microcode/intel: Extend BDW
late-loading with a revision check") to 4.4-stable deleted a "return true"
statement.  This bug is not present upstream or other stable branches.
