IIO: Documentation: iio_utils: Prevent buffer overflow

The first part of build_channel_array()identifies the number of enabled channels.
Further down this count is used to allocate the ci_array. The next section parses the
scan_elements directory again, and fills ci_array regardless if the channel is enabled or not.
So if less than available channels are enabled ci_array memory is overflowed.

This fix makes sure that we allocate enough memory. But the whole approach looks a bit
cumbersome to me. Why not allocate memory for MAX_CHANNLES, less say 64
(I never seen a part with more than that channels). And skip the first part entirely.

Staging: hv: add mouse driver

This driver adds mouse support to the hyper-v subsystem.

The code was originally written by Citrix, modified heavily by Hank at
Microsoft, and then further by me, to get it to build properly due to
all of the recent hyperv changes in the tree.

At the moment, it is marked "BROKEN" as it has not been tested well, and
it will conflict with other api changes that KY is doing, which I will
fix up later in this driver.

It still needs lots of work, and normal "cleanup".  I don't recommend
anyone running it on their machine unless they are very brave and know
how to debug kernel drivers in a hyperv system.

Staging: samsung-laptop: fix brightness level and add new device ids

The patch is against the 2.6.37 drivers/staging/samsung-laptop
driver and implements some extra enhancements.

It fixes an issue that the brightness would not change the level at
once as well as and some other oddities. It was resolved by
reallocated the SABI memory reagion using the "nocache" option.

especially the NC10plus which was used for testing this patch. This new
set of models also offer 9 instead of just 8 brightness levels so it
also introduces an additional parameter for the models struct so that

staging: brcm80211: removed locks around Mac80211 calls

A spinlock was acquired prior to calling the Mac80211 functions
ieee80211_wake_queues() and ieee80211_stop_queues() and Cfg80211 functions
wiphy_rfkill_set_hw_state() and wiphy_rfkill_start_polling().
This is not required and could even lead to instability. Therefore the locks
were removed.
