4.2.8-ckt12 -stable review patch. If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Itai Handler <redacted> 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).
