Subject: serial: 8250: omap: convert to modern PM ops
From: Arnd Bergmann <arnd@xxxxxxxx>
commit ae62c49c0ceff20dc7c1fad4a5b8f91d64b4f628 upstream.
The new uart_write() function is only called from suspend/resume code, causing
a build warning when those are left out:
drivers/tty/serial/8250/8250_omap.c:169:13: error: 'uart_write' defined but not used [-Werror=unused-function]
Remove the #ifdefs and use the modern pm_ops/pm_sleep_ops and their wrappers
to let the compiler see where it's used but still drop the dead code.
