Subject: [PATCH 1/5] OMAP3: l3: fix for "irq 10: nobody cared" message

From: [email-masked] (Omar Ramirez Luna)
Date: Tue, 29 Mar 2011 11:20:15 -0600

If an error occurs in the L3 on any other initiator than MPU,
the interrupt goes unhandled given that the 'base' register
was calculated with the initialized err_source value (which
coincidentally points to MPU) and not with the actual source
of the error.

Removed parenthesis that are not needed for the touched lines.
