[PATCH 11/18] tty: serial: samsung: don't compare with zero an if (bitwise expression)

[Tudor Ambarus]

Since an if tests the numeric value of an expression, certain coding
shortcuts can be used. The most obvious one is writing
    if (expression)
instead of
    if (expression != 0)

Since our case is a bitwise expression, it's more natural and clear to
use the ``if (expression)`` shortcut.
