This reverts commit 0aa525d1. The conditional RX-FIFO read seems to cause spurious interrupts and we see just: |serial8250: too much work for irq29 The previous behaviour was "default" for decades and Marvell's 88f6282 SoC might not be the only that relies on it. Therefore the Omap fix is reverted for now. Fixes: 0aa525d1 ("tty: serial: 8250_core: read only RX if there is something in the FIFO") Reported-By:
