Subject: [PATCH 4.19 25/95] tty: synclink_gt: rename a conflicting function name
From: Randy Dunlap <rdunlap@...radead.org>
[ Upstream commit 06e49073dfba24df4b1073a068631b13a0039c34 ]
'set_signals()' in synclink_gt.c conflicts with an exported symbol
in arch/um/, so change set_signals() to set_gtsignals(). Keep
the function names similar by also changing get_signals() to
get_gtsignals().
../drivers/tty/synclink_gt.c:442:13: error: conflicting types for ‘set_signals’
static void set_signals(struct slgt_info *info);
^~~~~~~~~~~
