[PATCH 07/10] tty: Convert ->dtr_rts() to take bool argument

From: Ilpo Järvinen
Date: Wed Jan 04 2023 - 10:17:30 EST

Convert the raise/on parameter in ->dtr_rts() to bool through the
callchain. The parameter is used like bool. In USB serial, there
remains a few implicit bool -> larger type conversions because some
devices use u8 in their control messages.
