From 510b9be374a4b589e7f6182d306b3c8ec9575e05 Mon Sep 17 00:00:00 2001 From: "J. Ali Harlow" Date: Wed, 18 May 2011 19:18:54 +0100 Subject: [PATCH] comedi vmk80xx: extend rudimentary_check to check both directions rudimentary_check() can currently check whether the input or output direction is currently available (no pending transaction), but not both at the same time. We need this facility for do_bits(). Signed-off-by: J.
