Subject: serial: 8250_dw: fix compilation warning when !CONFIG_PM_SLEEP
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=13b949f03e642c5df36ebf5b4770d75f8c4a6b09;p=linux.git

serial: 8250_dw: fix compilation warning when !CONFIG_PM_SLEEP

CONFIG_PM will be set if either or both CONFIG_PM_SLEEP and
CONFIG_PM_RUNTIME is set. Compiling the driver with !CONFIG_PM_SLEEP causes
following compilation warnings:

drivers/tty/serial/8250/8250_dw.c:404:12: warning: ‘dw8250_suspend’ defined but not used [-Wunused-function]
drivers/tty/serial/8250/8250_dw.c:413:12: warning: ‘dw8250_resume’ defined but not used [-Wunused-function]

Fix this by using CONFIG_PM_SLEEP instead.
