From 475fc6e2de6fec0ff3c9a74ddcfd2b52c90adc0d Mon Sep 17 00:00:00 2001 From: "Jiri Slaby (SUSE)" Date: Wed, 6 Dec 2023 08:37:08 +0100 Subject: tty: serdev: convert to u8 and size_t Switch character types to u8 and sizes to size_t. To conform to characters/sizes in the rest of the tty layer. This patch converts struct serdev_device_ops hooks and its instantiations.
