In commit c4004b02 ("x86: remove the kernel code/data/bss resources
from /proc/iomem") I was hoping to remove the phyiscal kernel address
data from /proc/iomem entirely, but that had to be reverted because some
system programs actually use it.

This limits all the detailed resource information to properly
credentialed users instead.

The PCI config access checked the file capabilities correctly, but used
the itnernal security capability check rather than the helper function
that is actually meant for that.

The security_capable() has unusual return values and is not meant to be
used elsewhere (the only other use is in the capability checking
functions that we actually intend people to use, and this odd PCI usage
really stood out when looking around the capability code.
Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

A lot of seqfile users seem to be using things like %pK that uses the
credentials of the current process, but that is actually completely
wrong for filesystem interfaces.

The unix semantics for permission checking files is to check permissions
at _open_ time, not at read or write time, and that is not just a small
detail: passing off stdin/stdout/stderr to a suid application and making
the actual IO happen in privileged context is a classic exploit
technique.

So if we want to be able to look at permissions at read time, we need to
use the file open credentials, not the current ones.  Normal file
accesses can just use "f_cred" (or any of the helper functions that do
that, like file_ns_capable()), but the seqfile interfaces do not have
any such options.

It turns out that seq_file _does_ save away the user_ns information of
the file, though.  Since user_ns is just part of the full credential
information, replace that special case with saving off the cred pointer
instead, and suddenly seq_file has all the permission information it
needs.

This reverts commit c4004b02.

Sadly, my hope that nobody would actually use the special kernel entries
in /proc/iomem were dashed by kexec.  Which reads /proc/iomem explicitly
to find the kernel base address.  Nasty.

Anyway, that means we can't do the sane and simple thing and just remove
the entries, and we'll instead have to mask them out based on permissions.

While the previous commit fixed the missing monitor_present flag
update, it may be still in an inconsistent state while the driver
repolls: the flag itself is updated, but the eld_valid flag and the
contents don't follow until the repoll finishes (and may be repeated
for a few times).

The basic problem is that pin_eld->monitor_present is updated in the
caller side.  This should have been updated only in update_eld().  So,
the proper fix is to avoid accessing pin_eld but only spec->temp_eld.
Signed-off-by: NTakashi Iwai <tiwai@suse.de>

The commit [bd481285: ALSA: hda - Fix forgotten HDMI
monitor_present update] covered the missing update of monitor_present
flag, but this caused a regression for devices without the i915 eld
notifier.  Since the old code supposed that pin_eld->monitor_present
was updated by the caller side, the hdmi_present_sense_via_verbs()
doesn't update the temporary eld->monitor_present but only
pin_eld->monitor_present, which is now overridden in update_eld().

The fix is to update pin_eld->monitor_present as well before calling
update_eld().

Note that this may still leave monitor_present flag in an inconsistent
state when the driver repolls, but this is at least the old behavior.
More proper fix will follow in the later patch.

This is Dell usb dock audio workaround.
It was fixed the master volume keep lower.

[Some background: the patch essentially skips the controls of a couple
 of FU volumes.  Although the firmware exposes the dB and the value
 information via the usb descriptor, changing the values (we set the
 min volume as default) screws up the device.  Although this has been
 fixed in the newer firmware, the devices are shipped with the old
 firmware, thus we need the workaround in the driver side.  -- tiwai]
