Due to recently merged patches and previous merge conflicts, the Samsung
PM Debug functionality no longer can be enabled. This patch fixes
incorrect dependency of SAMSUNG_PM_DEBUG on an integer symbol and adds
missing header inclusion.

Testing against 3.16-rc2, this doesn't quite work for me.
SAMSUNG_PM_DEBUG still doesn't appear in menuconfig.

HAVE_SAMSUNG_PM_DEBUG is 'n'. Looks like the select from
DEBUG_S3C_UART is not working, but I'm not sure why.

I hastily changed this to something simpler in last minute before
sending without proper testing. Let me send something that works.

Best regards,

Hmm...

The DEBUG_S3C_UART will be '0' when we select DEBUG_S3C_UART0, then the
HAVE_SAMSUNG_PM_DEBUG will not be selected so SAMSUNG_PM_DEBUG is also...

Yeah, this is required then we don't need inclusion <linux/serial_core.h> here.

Yes, that's right. I posted v2 after a while in another reply to this
thread.

I'm afraid you missed. V2 has been there since a long time posted as a
reply to original patch. You can find it here:
