[ Upstream commit 231ec2f24dad18d021b361045bbd618ba62a274e ]
Usually all the distro will load the parport low level driver as part
of their initialization. But we can get into a situation where all the
parallel port drivers are built as module and we unload all the modules
at a later time. Then if we just do "modprobe parport" it will only
load the parport module and will not load the low level driver which
will actually register the ports. So, check the bus if there is any
parport registered, if not, load the low level driver.We can get into the above situation with all distro but only Suse has
setup the alias for "parport_lowlevel" and so it only works in Suse.
Users of Debian based distro will need to load the lowlevel module
manually.Signed-off-by: Sudip Mukherjee

Pull char/misc driver updates from Greg KH:
"Here is the big char/misc driver pull request for 5.4-rc1.As has been happening in previous releases, more and more individual
driver subsystem trees are ending up in here. Now if that is good or
bad I can't tell, but hopefully it makes your life easier as it's more
of an aggregation of trees together to one merge point for you.Anyway, lots of stuff in here:

Pull Documentation updates from Jonathan Corbet:
"It's been a relatively busy cycle for docs:- A fair pile of RST conversions, many from Mauro. These create more
than the usual number of simple but annoying merge conflicts with
other trees, unfortunately. He has a lot more of these waiting on
the wings that, I think, will go to you directly later on.- A new document on how to use merges and rebases in kernel repos,
and one on Spectre vulnerabilities.- Various improvements to the build system, including automatic
markup of function() references because some people, for reasons I
will never understand, were of the opinion that
:c:func:``function()`` is unattractive and not fun to type.- We now recommend using sphinx 1.7, but still support back to 1.4.

The kbuild documentation clearly shows that the documents
there are written at different times: some use markdown,
some use their own peculiar logic to split sections.Convert everything to ReST without affecting too much
the author's style and avoiding adding uneeded markups.The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.Signed-off-by: Mauro Carvalho Chehab

This reverts commit 1aec4211204d9463d1fd209eb50453de16254599.
Steven Rostedt reports that it causes a hang at bootup and bisected it
to this commit.The troigger is apparently a module alias for "parport_lowlevel" that
points to "parport_pc", which causes a hang withmodprobe -q -- parport_lowlevel

sys_init_module+0xef/0x117Supid says:
"Due to the new device model daisy driver will now try to find the
parallel ports while trying to register its driver so that it can bind
with them. Now, since daisy driver is loaded while parport bus is
initialising the list of parport is still empty and it tries to load
the lowlevel driver, which has an alias set to parport_pc, now causes
a deadlock"But I don't think the daisy driver should be loaded by the parport
initialization in the first place, so let's revert the whole change.If the daisy driver can just initialize separately on its own (like a
driver should), instead of hooking into the parport init sequence
directly, this issue probably would go away.Reported-and-bisected-by: Steven Rostedt (VMware)

In the original code before 181bf1e815a2 the loop was continuing until
it finds the first matching superios[i].io and p->base.
But after 181bf1e815a2 the logic changed and the loop now returns the
pointer to the first mismatched array element which is then used in
get_superio_dma() and get_superio_irq() and thus returning the wrong
value.
Fix the condition so that it now returns the correct pointer.Fixes: 181bf1e815a2 ("parport_pc: clean up the modified while loops using for")

While here, remove init.h inclusion since we are not using it directly and

dev_warn() will print device name with associated driver,
no need to keep this open coded.While here, adjust indentation in the rest of dev_dbg() calls.

There is no need to repeat the work that is already done in the PCI
driver core. The patch removes excerpts from suspend and resume
callbacks.Note that there is no more calls performed to enable or disable a PCI
device during suspend-resume cycle. Nowadays they seems to be
superflous. Someone can read more in [1].While here, convert calls to new driver API.

a bit later. Thus omit the explicit initialisation at the beginning.Signed-off-by: Markus Elfring
