From fd2ada8db84435ddfd7374d3a0935bb927c11954 Mon Sep 17 00:00:00 2001 From: Lidza Louina Date: Wed, 21 Aug 2013 21:48:37 -0400 Subject: [PATCH] staging: dgap: tty.c: removes read_cnt, real_raw and rawreadok This patch removes the use of read_cnt, real_raw and rawreadok. These variables don't exist in the new API. Reading the data raw is no longer supported by the tty layer.
