From fffa35a25b4ced5ec89b1c12cf6a4f1d9541d3cb Mon Sep 17 00:00:00 2001 From: Hugo Villeneuve Date: Wed, 22 Nov 2023 12:58:59 -0500 Subject: serial: sc16is7xx: change confusing comment about Tx FIFO The comment wording can be confusing, as txlen will return the number of bytes available in the FIFO, which can be less than the maximum theoretical Tx FIFO size. Change the comment so that it is unambiguous.
