	  Say Y here if you want to build support for NFC (Near field
	  communication) devices.

	  To compile this support as a module, choose M here: the module will
	  be called nfc.

	default n
	help
	  Say Y if you want to build NFC digital protocol stack support.
	  This is needed by NFC chipsets whose firmware only implement
	  the NFC analog layer.

	  To compile this support as a module, choose M here: the module will
	  be called nfc_digital.

tracing: Fix hwlat kthread migration
The hwlat tracer creates a kernel thread at start of the tracer. It is pinned to a single CPU and will move to the next CPU after each period of running. If the user modifies the migration thread's affinity, it will not change after that happens. The original code created the thread at the first instance it was called, but later was changed to destroy the thread after the tracer was finished, and would not be created until the next instance of the tracer was established. The code that initialized the affinity was only called on the initial instantiation of the tracer. After that, it was not initialized, and the previous affinity did not match the current newly created one, making it appear that the user modified the thread's affinity when it did not, and the thread failed to migrate again.
