Subject: [PATCH 1/5] OMAP3: l3: fix for "irq 10: nobody cared" message
Date: Tue, 29 Mar 2011 11:20:15 -0600	[thread overview]
Message-ID: <1301419219-30547-2-git-send-email-omar.ramirez@ti.com> (raw)
In-Reply-To: <1301419219-30547-1-git-send-email-omar.ramirez@ti.com>

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.
