Aaro Koskinen 9eb13cf3ec i2c: omap: fix draining irq handling ... Commit 0bdfe0cb80 (i2c: omap: sanitize exit path) changed the interrupt handler to exit early and complete the transfer after the draining IRQ is handled. As a result, the ARDY may not be cleared properly, and it may cause all future I2C transfers to timeout with "timeout waiting for bus ready". This is reproducible at least with N900 when twl4030_gpio makes a long write (> FIFO size) during the probe (http://marc.info/?l=linux-omap&m=135818882610432&w=2). The fix is to continue until we get ARDY interrupt that completes the transfer. Tested with 3.8-rc4 + N900: 20 boots in a row without errors; without the patch the problem triggers after few reboots.
