Subject: media: rc: remove unused tx_resolution field
Author: Sean Young <s...@mess.org>
Date: Sun Jun 30 22:33:44 2024 +0100
The tx_resolution field is never read. In theory you can imagine this
field being useful for detecting whether the transmitter has the
resolution for the message you are trying to send, but I am not aware of
any hardware where this could be an issue.
Just remove.
