Subject: [PATCH 3/3] drivers:misc:ti-st: fix skip remote baud logic

From: Victor Goldenshtein <victorg@...com>

Texas Instruments WiLink connectivity combo chipsets support custom baud
rates over its UART interface.
This can be achieved by sending the change remote baud rate command.
Since the baud rate can be properly set by the user-space on shared
transport the remote chip-side and local host-side baud rate is change
by the User Space Init Manager.

This patch when encounters the same command inside the firmware,
attempts to skip such command since it is handled by the user-space.
The logic to skip the command when it is un-commented is fixed by this
patch.
