In normal measurement configuration the device
follows normal measurement flow. Pins BP and BN
are left floating and high impedance.

positivebias -  Positive bias configuration: In positive bias
configuration, a positive current is forced across
the resistive load on pins BP and BN.

negativebias -  Negative bias configuration. In negative bias
configuration, a negative current is forced across
the resistive load on pins BP and BN.

drivers/staging/android: don't use modular references in sync_debug.c

In commit 8a0044846115e74552b671a7073cffeec14b9316 ("staging/android:
create a 'sync' dir for debugfs information"), modular references were
introduced to this file.  However if we look, we find:

drivers/staging/android/Makefile:obj-$(CONFIG_SYNC) += sync.o sync_debug.o

drivers/staging/android/Kconfig:config SYNC
drivers/staging/android/Kconfig:        bool "Synchronization framework"

This file isn't currently buildable as a module, and hence the code
for module_exit is just dead code.  Remove it and the module.h include.
