Subject: [PATCH 2/6] staging: vt6655: parse bb vga code out of device_intr.
Date: Sun, 1 Feb 2015 11:59:39 +0000 [thread overview]
Message-ID: <1422791983-3408-2-git-send-email-tvboxspy@gmail.com> (raw)
In-Reply-To: <1422791983-3408-1-git-send-email-tvboxspy@gmail.com>
Reordering the code and reversing the priv->byBBVGANew verses
priv->byBBVGACurrent check and using dev_dbg for pr_debug.
