Corentin Chary 774b06780b asus-laptop: control how BLED and WLED should be exposed
Let the user tells if BLED and WLED should be exposed as led or
rfkill (the old sysfs are still here, but this adds a standard
interface to control the device).

For example on my A6JC, with WAPF=1, I would do:

$ modprobe asus-laptop wled_type=led bluetooth_type=rfkill

There is still no known way to automatically guess what BLED
and WLED methods will control, it's why user information is needed.

A userspace database could do that automatically, and maybe some DMI
matching in the driver.

Corentin Chary 3be324a94d samsung-laptop: make the dmi check less strict
This enable the driver for everything that look like
a laptop and is from vendor "SAMSUNG ELECTRONICS CO., LTD.".
Note that laptop supported by samsung-q10 seem to have a different
vendor strict.

Also remove every log output until we know that we have a SABI interface
(except if the driver is forced to load, or debug is enabled).

Keeping a whitelist of laptop with a model granularity is something that can't
work without close vendor cooperation (and we don't have that).

samsung-laptop is not at all related to ACPI, but since this interface
is not documented at all, and the driver has to use it at load to
understand how it works on the laptop, I think it's a good idea to
disable it if a better solution is available.

John Hughes 747a562f34 to fix scancodes returned by sony-laptop driver
Fix scancodes returned by driver to match scancodes used to remap keys.

(Before the patch FN/E returned scancode 0x1B, but to remap scancode
0x14 had to be used).

The scancodes returned by the sony-laptop driver for function keys did not
match the scancodes used to remap keys.  Also, since the scancode was sent
to the input subsystem after the mapped keysym the /lib/udev/keymap
utility was confused about which scancode to report for which keysym.

This patch fixes the driver so the correct scancode is shown for each
key.  It also adds to the documentation a description of where to find
the scancodes.

Josh Boyer 6fe6ae56a7 sony-laptop: Enable keyboard backlight by default
When the keyboard backlight support was originally added, the commit said
to default it to on with a 10 second timeout.  That actually wasn't the
case, as the default value is commented out for the kbd_backlight parameter.
Because it is a static variable, it gets set to 0 by default without some
other form of initialization.

However, it seems the function to set the value wasn't actually called
immediately, so whatever state the keyboard was in initially would remain.
Then commit df410d5224 was introduced during the 2.6.39 timeframe to
immediately set whatever value was present (as well as attempt to
restore/reset the state on module removal or resume).  That seems to have
now forced the light off immediately when the module is loaded unless
the option kbd_backlight=1 is specified.

Let's enable it by default again (for the first time).  This should solve

 "1) icmp6_dst_alloc() returns NULL instead of ERR_PTR() leading to

  2) hyperv and wimax/i2400m return NETDEV_TX_BUSY when they have

     means requeue the packet.  Fixes from Eric Dumazet.

  3) usbnet driver doesn't allocate the right amount of headroom on

  4) Fix regression in ip6_mc_find_dev_rcu(), as an RCU lookup it

     leaks.  Fix from RonQing Li.

  5) Fix netfilter ctnetlink race between delete and timeout expiration.

Linus Torvalds 0c48ca8512 Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm exynos/intel updates from Dave Airlie:
 "Two minor updates from Jesse for Intel SNB fixes, and a few fixes from
  Samsung for exynos.  The pull req has Alan's commit in it since Intel
  based their tree on my tree at that time, but it all seems fine wrt
  merging."

Linus Torvalds 72c79bdbda Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media fixes from Mauro Carvalho Chehab:
 "For 4 fixes for 3.3 (all trivial):
       - uvc video driver: fixes a division by zero;
       - davinci: add module.h to fix compilation;
       - smsusb: fix the delivery system setting;
       - smsdvb: the get_frontend implementation there is broken.

  The smsdvb patch has 127 lines, but it is trivial: instead of
  returning a cache of the set_frontend (with is wrong, as it doesn't
  have the updated values for the data, and the implementation there is
  buggy), it copies the information of the detected DVB parameters from
  the smsdvb private structures into the corresponding DVBv5 struct
  fields."

Linus Torvalds fe83558a33 Merge branch '3.3-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull target fixes from Nicholas Bellinger:
 "This series addresses two recently reported regression bugs related to
  legacy SCSI reservation usage in target core, and iscsi-target
  reservation conflict handling.

  The second patch in particular addresses possible data-corruption with
  SCSI reservations that is specific to iscsi-target fabric LUNs with
  multiple client writers.  Both patches need to go into v3.2 stable
  ASAP, and the branch based on the last target-pending/3.3-rc-fixes
  HEAD.

  Again, thanks to Martin Svec for his help to identify and address this
  regression bug with iscsi-target."

Dan Carpenter cf2b94daab drivers/video/backlight/s6e63m0.c: fix corruption storing gamma mode
strict_strtoul() writes a long but ->gamma_mode only has space to store an
int, so on 64 bit systems we end up scribbling over ->gamma_table_count as
well.  I've changed it to use kstrtouint() instead.

Alexandre Bounine 9bbad7da76 rapidio/tsi721: fix bug in register offset definitions
Fix indexed register offset definitions that use decimal (wrong) instead
of hexadecimal (correct) notation for indexing multipliers.

Incorrect definitions do not affect Tsi721 driver in its current default
configuration because it uses only IDB queue 0.  Loss of inbound
doorbell functionality should be observed if queue other than 0 is used.

Ville Syrjala 8ee161ce5e i2c-algo-bit: Fix spurious SCL timeouts under heavy load
When the system is under heavy load, there can be a significant delay
between the getscl() and time_after() calls inside sclhi(). That delay
may cause the time_after() check to trigger after SCL has gone high,
causing sclhi() to return -ETIMEDOUT.

To fix the problem, double check that SCL is still low after the
timeout has been reached, before deciding to return -ETIMEDOUT.

Sascha Hauer 34418c25d6 drm exynos: use drm_fb_helper_set_par directly
info->fix.visual already is correctly set from drm_fb_helper_fill_fix.
info->fix.line_length is also set from drm_fb_helper_fill_fix,
so drm_fb_helper_set_par directly instead of a custom
exynos_drm_fbdev_set_par.
