From 7496e0538666012b89d2280f3f6681345002a454 Mon Sep 17 00:00:00 2001 From: Mark Hounschell Date: Fri, 25 Apr 2014 13:10:18 -0400 Subject: [PATCH] staging: dgap: check unchecked return values Check the return values of dgap_tty_register and dgap_finalize_board_init. If they fail for a particular board we should not be able to try to use that board. IE. no device entries shall be created for that board.
