From c27fc351cf4298b5ade8f3bda8f8be15af5d6cde Mon Sep 17 00:00:00 2001 From: Christian Gromm Date: Wed, 28 Oct 2015 15:14:35 +0100 Subject: [PATCH] staging: most: remove exclusive wait_queue This patch removes the unnecessary wait_queue that has exclusively been used for the poll function and its poll_table. Instead, an already existing one is used.
