Subject: [PATCH] Staging: speakup: Clear hi font bit from attributes
Date: Tue, 15 Mar 2016 21:34:59 +0100 [thread overview]
Message-ID: <20160315203459.GR3553@var.home> (raw)
Previously, speakup would see the hi-font bit in attributes.
Since this bit has nothing to do with attributes, we need to clear it.
