From 5e86bfde9cd93f272844c3ff6ac5f93d3666b3e7 Mon Sep 17 00:00:00 2001 From: Arseny Solokha Date: Tue, 24 Feb 2015 16:05:06 +0700 Subject: powerpc/mpic: remove unused functions Drop unused fsl_mpic_primary_get_version(), mpic_set_clk_ratio(), mpic_set_serial_int(). + fsl_mpic_primary_get_version() is just a safe wrapper around fsl_mpic_get_version() for SMP configurations. While the latter is called explicitly for handling PIC initialization and setting up error interrupt vector depending on PIC hardware version, the former isn't used for anything. + As for mpic_set_clk_ratio() and mpic_set_serial_int(), they both are almost nine years old[1] but still have no chance to be called even from out-of-tree modules because they both are __init and of course aren't exported.
