From 47a7e5e97d4edd7b14974d34f0e5a5560fad2915 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Mon, 30 Sep 2019 19:15:12 -0700 Subject: [PATCH] tty: n_hdlc: fix build on SPARC Fix tty driver build on SPARC by not using __exitdata. It appears that SPARC does not support section .exit.data. Fixes these build errors: `.exit.data' referenced in section `.exit.text' of drivers/tty/n_hdlc.o: defined in discarded section `.exit.data' of drivers/tty/n_hdlc.o `.exit.data' referenced in section `.exit.text' of drivers/tty/n_hdlc.o: defined in discarded section `.exit.data' of drivers/tty/n_hdlc.o `.exit.data' referenced in section `.exit.text' of drivers/tty/n_hdlc.o: defined in discarded section `.exit.data' of drivers/tty/n_hdlc.o `.exit.data' referenced in section `.exit.text' of drivers/tty/n_hdlc.o: defined in discarded section `.exit.data' of drivers/tty/n_hdlc.o Reported-by: kbuild test robot Fixes: 063246641d4a ("format-security: move static strings to const") Signed-off-by: Randy Dunlap Cc: Kees Cook Cc: Greg Kroah-Hartman Cc: "David S.
