* tty: fix up a few remaining files without SPDX identifiersGreg Kroah-Hartman2019-04-041-0/+1
| | | | | | | | | | | | | | | | | | | There were a few straggling files under drivers/tty/ that did not have any SPDX identifier either because they entered the tree recently, or they somehow missed the mass-tagging of commit b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") This commit follows the same rule as b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") where files without any specified license in them fall under GPL-2.0 as the correct license for the individual file. Add that identifier to these remaining files so that we don't have to guess at the license of them in the future. Cc: Jiri Slaby <jslaby@suse.com> Cc: "David S.

| | | | | | | | | | | | In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.
