Revision ca8bb4aefb932e3da105f28cbfba36d57a931081 authored by Sebastian Andrzej Siewior on 15 February 2015, 17:32:16 UTC, committed by Greg Kroah-Hartman on 07 March 2015, 02:06:51 UTC
This reverts commit 0aa525d11859c1a4d5b78fdc704148e2ae03ae13.
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: 0aa525d11859 ("tty: serial: 8250_core: read only RX if there is
something in the FIFO")
