Subject: [PATCH 5.15 279/846] um: rename set_signals() to um_set_signals()
From: Johannes Berg <johannes.berg@...el.com>
[ Upstream commit bbe33504d4a7fdab9011211e55e262c869b3f6cc ]
Rename set_signals() as there's at least one driver that
uses the same name and can now be built on UM due to PCI
support, and thus we can get symbol conflicts.
Also rename set_signals_trace() to be consistent.
Reported-by: kernel test robot <lkp@...el.com>
Fixes: 68f5d3f3b654 ("um: add PCI over virtio emulation driver")
