Subject: [PATCH 01/16] TTY: jsm, remove superfluous check
Date: Thu, 7 Mar 2013 13:12:25 +0100 [thread overview]
Message-ID: <1362658360-26629-1-git-send-email-jslaby@suse.cz> (raw)
data_len in jsm_input cannot be zero as we would jump out early in the
function. It also cannot be negative because it is an int and we do
bitwise and with 8192. So remove the check.
