Masahiro Yamada a17e3bbfb9 i2c: uniphier-f: fix race condition when IRQ is cleared ... [ Upstream commit eaba68785c ] The current IRQ handler clears all the IRQ status bits when it bails out. This is dangerous because it might clear away the status bits that have just been set while processing the current handler. If this happens, the IRQ event for the latest transfer is lost forever. The IRQ status bits must be cleared *before* the next transfer is kicked.
