[PATCH] tty: caif: removed unused function debugfs_tx()

From: Simon Horman
Date: Thu Mar 20 2025 - 07:21:24 EST


Remove debugfs_tx() which was added when the caif driver was added in
commit 9b27105b4a44 ("net-caif-driver: add CAIF serial driver (ldisc)")
but it has never been used.

Flagged by LLVM 19.1.7 W=1 builds.
