[PATCH] thermal: ti-soc-thermal: fix compilation warnings when !CONFIG_PM_SLEEP

[Paul Walmsley]

When CONFIG_PM_SLEEP=n, the following compilation warnings appear:

drivers/thermal/ti-soc-thermal/ti-bandgap.c:1478:12: warning: ‘ti_bandgap_suspend’ defined but not used [-Wunused-function]
 static int ti_bandgap_suspend(struct device *dev)
            ^
drivers/thermal/ti-soc-thermal/ti-bandgap.c:1492:12: warning: ‘ti_bandgap_resume’ defined but not used [-Wunused-function]
 static int ti_bandgap_resume(struct device *dev)

A few years ago, suspend/resume-related code was protected by CONFIG_PM.  
But that was changed and now it's protected by CONFIG_PM_SLEEP.  Fix the 
warnings by converting the preprocessor test in the TI bandgap thermal 
sensor driver from testing CONFIG_PM to testing CONFIG_PM_SLEEP.

Non-critical.  Targeted for either v3.20-rc1 or v3.21-rc1.

Basic test reports for a series that includes this patch (and a few other 
unrelated warning cleanups) is available here:

I am a little confused:
https://patchwork.kernel.org/patch/5792411/ was already posted. would
you suggest improvements?

Oh, nothing to be confused by, I just missed the earlier patch.  I 
withdraw mine.
