Message-Id: <1279794727-7669-2-git-send-email-pavan_savoy@ti.com>
Date: Thu, 22 Jul 2010 05:32:05 -0500
From: pavan_savoy@...com
To: gregkh@...e.de, alan@...rguk.ukuu.org.uk

Subject: [PATCH 1/3] drivers:staging:ti-st: smarten, reduce logs
From: Pavan Savoy <pavan_savoy@...com>
Replace looping on the data buffers and printk-ing by
print_hex_dump.
Also replace most of the pr_info by pr_debug to reduce logging at
default loglevels (7 in our case..)
