I tested on latest kernel today one more time, there is no error and warning on my side, not only patch 1/3 and patch 3/3 Line 1735: CC drivers/tty/serial/samsung_tty.o Line 343: CC drivers/tty/serial/samsung_tty.o wr_reg_barrier is not defined in patch 1/3, and wr_reg_barrier is define and used in patch3/3 it might be no warning.
