The code is mirrorred in scrolldelta implementations of both vgacon
and sisusb. Let's move the code to a separate helper where we will
perform a common cleanup and further changes.
While we are moving the code, make it linear and save one indentation
level. This is done by returning from the "!lines" then-branch
immediatelly. This allows flushing the else-branch 1 level to the
left, obviously.
Few more new lines and comments were added too.
And do not forget to export the helper function given sisusb can be
built as module.

Scrolling helpers scrup and scrdown both accept 'top' and 'bottom' as
unsigned int. Number of lines 'nr' is accepted as int, but all callers
pass down unsigned too. So change the type of 'nr' to unsigned too.
Now, promote unsigned int from the helpers up to the con_scroll
hook which actually accepted all those as signed int.
Next, the 'dir' parameter can have only two values and we define
constants for that: SM_UP and SM_DOWN. Switch them to enum and do
proper type checking on 'dir' too.
Finally, document the behaviour of the hook.

After commit b09b5224fe ("usb: chipidea: implement platform shutdown
callback") and commit 43a404577a ("usb: chipidea: host: set host to
be null after hcd is freed") a NULL pointer dereference is caused
on i.MX23 during shutdown. So ensure that role is set to CI_ROLE_END and
we finish interrupt handling before the hcd is deallocated. This avoids
the NULL pointer dereference.

Changing the LCR register after initialization does not seem to be reliable
on all chips (particularly not on CH341A). Restructure initialization and
configuration to always reinit the chip on configuration changes instead and
pass the LCR register value directly to the initialization command.
(Note that baud rates above 500kbaud are incorrect, but they're incorrect in
the same way both before and after this patch at least on the CH340G. Fixing
this isn't a priority as higher baud rates don't seem that reliable anyway.)

If we configure musb with 2430 glue as a peripheral, and then rmmod
omap2430 module, we'll get the following error:
[ INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected ]
...
rmmod/413 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
(&phy->mutex){+.+.+.}, at: [<c04b9fd0>] phy_power_off+0x1c/0xb8

and this task is already holding:
(&(&musb->lock)->rlock){-.-...}, at: [<bf3a482c>]
musb_gadget_stop+0x24/0xec [musb_hdrc]
which would create a new lock dependency:
(&(&musb->lock)->rlock){-.-...} -> (&phy->mutex){+.+.+.}
...
This is because some glue layers expect musb_platform_enable/disable
to be called with spinlock held, and 2430 glue layer has USB PHY on
the I2C bus using a mutex.
We could fix the glue layers to take the spinlock, but we still have
a problem of musb_plaform_enable/disable being called in an unbalanced
manner. So that would still lead into USB PHY enable/disable related
problems for omap2430 glue layer.
While it makes sense to only enable USB PHY when needed from PM point
of view, in this case we just can't do it yet without breaking things.
So let's just revert phy_enable/disable related changes instead and
reconsider this after we have fixed musb_platform_enable/disable to
be balanced.

This patch adds support for the GPIO found on the CP2105. Unlike the GPIO
provided by some of the other devices supported by the cp210x driver, the
GPIO on the CP2015 is muxed on pins otherwise used for serial control
lines. The GPIO have been configured in 2 separate banks as the choice to
configure the pins for GPIO is made separately for pins shared with each
of the 2 serial ports this device provides, though the choice is made for
all pins associated with that port in one go. The choice of whether to use
the pins for GPIO or serial is made by adding configuration to a one-time
programable PROM in the chip and can not be changed at runtime. The device
defaults to GPIO.
This device supports either push-pull or open-drain modes, it doesn't
provide an explicit input mode, though the state of the GPIO can be read
when used in open-drain mode. Like with pin use, the mode is configured in
the one-time programable PROM and can't be changed at runtime.

usb: fixes for v4.9-rc2
First set of fixes for v4.9-rc cycle. Nothing major
this time around. The most important patches are the
3 fixes in dwc3 (dma_free_coheren() size fix,
queued request accounting fix and Isochronous
StartTransfer fix) and the 3 reverts on dwc2.
We're also including the late atmel UDC fix which
didn't make it into v4.8-final.
This reverts commit aa381a7259 ("usb: dwc2: gadget: fix TX FIFO size
and address initialization").
The original commit removed the FIFO size programming per endpoint. The
DPTXFSIZn register is also used for DIEPTXFn and the SIZE field is r/w
in dedicated fifo mode. So it isn't appropriate to simply remove this
initialization as it might break existing behavior.
Also, some cores might not have enough fifo space to handle the
programming method used in the reverted patch, resulting in fifo
initialization failure.

Pull ARM SoC late DT updates from Arnd Bergmann:
"These updates have been kept in a separate branch mostly because they
rely on updates to the respective clk drivers to keep the shared
header files in sync.
- The Renesas r8a7796 (R-Car M3-W) platform gets added, this is an
automotive SoC similar to the ⅹ8a7795 chip we already support, but
the dts changes rely on a clock driver change that has been merged
for v4.9 through the clk tree.
- The Amlogic meson-gxbb (S905) platform gains support for a few
drivers merged through our tree, in particular the network and usb
driver changes are required and included here, and also the clk
tree changes.
- The Allwinner platforms have seen a large-scale change to their clk
drivers and the dts file updates must come after that. This
includes the newly added Nextthing GR8 platform, which is derived
from sun5i/A13.
- Some integrator (arm32) changes rely on clk driver changes.
- A single patch for lpc32xx has no such dependency but wasn't added
until just before the merge window"
