From: Hugo Villeneuve Date: Wed, 22 Nov 2023 17:59:56 +0000 (-0500) Subject: serial: max310x: change confusing comment about Tx FIFO X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1be5f0819c1adc8308ecdc248314c5f30c994452;p=linux.git serial: max310x: 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.
