Clang warns:
drivers/s390/net/ism_drv.c:570:12: warning: unused function
'ism_suspend' [-Wunused-function]
static int ism_suspend(struct device *dev)
^
drivers/s390/net/ism_drv.c:578:12: warning: unused function 'ism_resume'
[-Wunused-function]
static int ism_resume(struct device *dev)
^
2 warnings generated.
When CONFIG_PM is unset, SIMPLE_DEV_PM_OPS does not use the suspend or
resume functions. Power management was recently ripped out of s390 so
CONFIG_PM will never be set and these functions will always be unused.
Remove them so that there is no more warning.
