From ea656980f40d599400d2306b23f2fbc707ae7313 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Fri, 17 Oct 2008 18:09:16 +0200 Subject: [PATCH] sgiioc4: remove maskproc() method Since the maskproc() method calls either mirror the interrupt en/disable via the nIEN bit of the device control register done by the IDE core before issuing a command or unmask the interrupt after a command executed in polled mode (when interrupt is already not expected), it is pointless to implement this method by manipulating the nIEN bit...
