From: Greg Kroah-Hartman
Date: Sun Jun 05 2016 - 18:29:06 EST

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


From: Itai Handler <itai_handler@xxxxxxxxxxx>

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).
