Subject: [PATCH 3.12 43/56] drm/gma500: Fix possible out of bounds read

From: Itai Handler <itai_handler@...mail.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 7ccca1d5bf69fdd1d3c5fcf84faf1659a6e0ad11 upstream.

Fix possible out of bounds read, by adding missing comma.
The code may read pass the end of the dsi_errors array
when the most significant bit (bit #31) in the intr_stat register
is set.
This bug has been detected using CppCheck (static analysis tool).
