From c643794eb3b57116924eadb40bbc34296b49d401 Mon Sep 17 00:00:00 2001 From: Daeseok Youn Date: Mon, 18 Aug 2014 23:32:36 +0900 Subject: [PATCH] staging: dgap: remove useless a variable within board_t The use_interrupts is used only in dagp_request_irq() for checking a value from user config file. It doesn't need in board_t struct.
