something in the FIFO"
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")

The exact same code was added in commit 3239fd31d4 (serial: of-serial: fetch

The tsi148 driver is registering the slave images as supporting the "USER"
access modes and CR/CSR access mode rather than the master images as it
should.
Remove the incorrect case entries for these modes from the
tsi148_slave_set() function, stop registering slave_images as supporting
these modes and instead register master windows as supporting these modes.

Pull drm fixes from Dave Airlie:
"Radeon, imx, msm, and i915 fixes.
The msm, imx and i915 ones are fairly run of the mill.
Radeon had some DP audio and posting reads for irq fixes, along with a
fix for 32-bit kernels with new cards, we were using unsigned long to
represent GPU side memory space, but since that changed size on 32 vs
64 cards with lots of VRAM failed, so the change has no effect on
x86-64, just moves to using uint64_t instead"

Remove the LOGERR, LOGERRDEV, LOGERRDEVX, LOGERRNAME, LOGORDUMPERR
macros from all the drivers.
In one case the removal of the ERRDRV() changed things such that a macro which
returned a value was needed, but the return value was no longer being used. In
this case the macro was replaced with the contents of the macro, but with the
truth calculation removed so that it would not generate a warning.
