5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>
commit c53aab20762255ee03e65dd66b3cba3887ad39d1 upstream.
If CONFIG_PM is not set (e.g. m68k/allmodconfig):
drivers/tty/serial/8250/8250_omap.c:169:13: error: ‘uart_write’ defined but not used [-Werror=unused-function]
169 | static void uart_write(struct omap8250_priv *priv, u32 reg, u32 val)
| ^~~~~~~~~~
Fix tis by moving uart_write() inside the existing section protected
by #ifdef CONFIG_PM.
