From c2f90a465df75254fb41bf6e7975464929c21e26 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 3 May 2016 17:16:22 +0200 Subject: [PATCH] HSI: omap-ssi: move omap_ssi_port_update_fclk After the clk change support, the ssi omap ssi core driver now calls into the port driver to change fclk. This function was previously inside of an #ifdef, because it was only used when CONFIG_PM is enabled. Now it also gets used without power management support: drivers/hsi/built-in.o: In function `ssi_clk_event': omap_ssi_port.c:(.text+0x1bf8): undefined reference to `omap_ssi_port_update_fclk' This moves the function outside of the CONFIG_PM guard.
