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. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Fixes: 4bcf7414528a ("HSI: omap-ssi: add clk change support") Signed-off-by: Sebastian Reichel <sre@kernel.org>
