Subject: [PATCH 4.9 12/44] MIPS: ralink: Remove unused timer functions

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

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

From: Arnd Bergmann <arnd@...db.de>

commit d92240d12a9c010e0094bbc9280aae4a6be9a2d5 upstream.

The functions were originally used for the module unload path,
but are not referenced any more and just cause warnings:

arch/mips/ralink/timer.c:104:13: error: 'rt_timer_disable' defined but not used [-Werror=unused-function]
arch/mips/ralink/timer.c:74:13: error: 'rt_timer_free' defined but not used [-Werror=unused-function]
