====================
netfilter updates for net-next
First patch, from myself, is a bug fix. The issue (connect timeout) is
ancient, so I think its safe to give this more soak time given the esoteric
conditions needed to trigger this.
Also updates the existing selftest to cover this.
Add netlink extacks when an update references a non-existent
table/chain/set. This allows userspace to provide much better
errors to the user, from Pablo Neira Ayuso.
Last patch adds more policy checks to nf_tables as a better
alternative to the existing runtime checks, from Phil Sutter.

Having sgtl5000_clk defines as "fixed-clock" is not enough to prevent
the dai subsystem from overwriting the frequency via sgtl5000_set_dai_sysclk.
Setting system-clock-fixed does the job, and now a 1kHz sine wave
comes out as actually 1kHz, no matter the sample rate of the source.
Testcase: These should sound the same:
speaker-test -r 48000 -t sine -f 1000
speaker-test -r 24000 -t sine -f 1000
Also remove the clock link here as having it in sgtl5000 and
sgtl5000_codec causes duplicate clock unprepares with associated
backtrace.

Instead of having a descriptor for every file represented in the eventfs
directory, only have the directory itself represented. Change the API to
send in a list of entries that represent all the files in the directory
(but not other directories). The entry list contains a name and a callback
function that will be used to create the files when they are accessed.
struct eventfs_inode *eventfs_create_events_dir(const char *name, struct dentry *parent,
const struct eventfs_entry *entries,
int size, void *data);
is used for the top level eventfs directory, and returns an eventfs_inode
that will be used by:
struct eventfs_inode *eventfs_create_dir(const char *name, struct eventfs_inode *parent,
const struct eventfs_entry *entries,
int size, void *data);
where both of the above take an array of struct eventfs_entry entries for
every file that is in the directory.
The entries are defined by:
typedef int (*eventfs_callback)(const char *name, umode_t *mode, void **data,
const struct file_operations **fops);
struct eventfs_entry {
const char *name;
eventfs_callback callback;
};
Where the name is the name of the file and the callback gets called when
the file is being created. The callback passes in the name (in case the
same callback is used for multiple files), a pointer to the mode, data and
fops. The data will be pointing to the data that was passed in
eventfs_create_dir() or eventfs_create_events_dir() but may be overridden
to point to something else, as it will be used to point to the
inode->i_private that is created. The information passed back from the
callback is used to create the dentry/inode.
If the callback fills the data and the file should be created, it must
return a positive number. On zero or negative, the file is ignored.
This logic may also be used as a prototype to convert entire pseudo file
systems into just-in-time allocation.
The "show_events_dentry" file has been updated to show the directories,
and any files they have.
With just the eventfs_file allocations:

Currently the struct "rt5033_charger_data" is initialized rather complicated.
The cause lies inside of the struct "rt5033_charger", where struct
"rt5033_charger_data" is implemented as a pointer *chg.
Therefore, inside of struct "rt5033_charger" change the struct
"rt5033_charger_data" to non-pointer "chg". It is then initialized right

Implement cable detection by extcon and handle the driver according to the
connector type.
There are basically three types of action: "set_charging", "set_otg" and
"set_disconnect".
A forth helper function to "unset_otg" was added because this is used in both
"set_charging" and "set_disconnect". In the first case it covers the rather
rare event that someone changes from OTG to charging without disconnect. In
the second case, when disconnecting, the values are set back to the ones from
initialization to return into a defined state.
Additionally, there is "set_mivr". When connecting to e.g. a laptop/PC, the
minimum input voltage regulation (MIVR) shall prevent a voltage drop if the
cable or the supply is weak. The MIVR value is set to 4600MV, same as in the
Android driver [1]. When disconnecting, MIVR is set back to DISABLED.
In the function rt5033_get_charger_state(): When in OTG mode, the chip
reports status "charging". Change this to "discharging" because there is
no charging going on in OTG mode [2].
Yang Yingliang detected missing mutex_unlock() in some error path and
suggested a fix [3]. The suggestion was squashed into this patch.
