From 2158a09395b3751db99663b2efdcce0ae09ca133 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 19 Apr 2017 23:43:10 +0200 Subject: [PATCH] clk: ti: fix linker error with !SOC_OMAP4 When none of the OMAP4-generation SoCs are enabled, we run into a link error for am43xx/am43xx: drivers/clk/ti/dpll.o: In function `of_ti_am3_dpll_x2_setup': dpll.c:(.init.text+0xd8): undefined reference to `clkhwops_omap4_dpllmx' This is easily fixed by adding another #ifdef. While looking at the code, I also spotted another problem with the assignment of hw_ops variable that is not used again later. I'm changing this to setting clk_hw->ops instead, which I guess is what was intended here.
