Alexandre Bounine 13bbf8c9ea rapidio/tsi721: fix bug in MSI interrupt handling ... commit 1ccc819da6fda9bee10ab8b72e9adbb5ad3e4959 upstream. Fix bug in MSI interrupt handling which causes loss of event notifications. Typical indication of lost MSI interrupts are stalled message and doorbell transfers between RapidIO endpoints. To avoid loss of MSI interrupts all interrupts from the device must be disabled on entering the interrupt handler routine and re-enabled when exiting it. Re-enabling device interrupts will trigger new MSI message(s) if Tsi721 registered new events since entering interrupt handler routine. This patch is applicable to kernel versions starting from v3.2.
