Subject: [PATCH 01/36] tty: serdev: core: Remove unused variable 'dummy'

No need to have a dummy variable here.

Fixes the following W=1 kernel build warning(s):

 drivers/tty/serdev/core.c: In function ‘serdev_controller_remove’:
 drivers/tty/serdev/core.c:791:6: warning: variable ‘dummy’ set but not used [-Wunused-but-set-variable]
