[PATCH 3/4] ARM: clps711x: Fix lowlevel debug-macro

[Alexander Shiyan]

CTS signal can not be used for the port and tied to any logic state.
In this case we have an infinite loop waiting for the signal. For fix
this problem, checking CTS removed, waiting for the signal "busy" was
postponed after the byte write to the port.
