From cfc7c12b508ac0a4ebf20a187e471e5b1dc6402c Mon Sep 17 00:00:00 2001 From: "Jiri Slaby (SUSE)" Date: Thu, 10 Aug 2023 11:15:07 +0200 Subject: [PATCH] tty: vcc: convert counts to size_t Unify the type of tty_operations::write() counters with the 'count' parameter. I.e. use size_t for them. This includes changing vcc_port::chars_in_buffer to size_t to keep min() and avoid min_t(). Signed-off-by: "Jiri Slaby (SUSE)" Cc: "David S.
