Subject: [PATCH] tty: n_hdlc: fix build on SPARC
Date: Mon, 30 Sep 2019 19:15:12 -0700
Message-ID: <675e7bd9-955b-3ff3-1101-a973b58b5b75@infradead.org> (raw)

From: Randy Dunlap <rdunlap@infradead.org>

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
