----------------------------
-What: Removing the pn544 raw driver.
-When: 3.6
-Why: With the introduction of the NFC HCI and SHDL kernel layers, pn544.c
- is being replaced by pn544_hci.c which is accessible through the netlink
- and socket NFC APIs. Moreover, pn544.c is outdated and does not seem to
- work properly with the latest Android stacks.
- Having 2 drivers for the same hardware is confusing and as such we
- should only keep the one following the kernel NFC APIs.
-Who: Samuel Ortiz <sameo@linux.intel.com>

What: setitimer accepts user NULL pointer (value)
When: 3.6
Why: setitimer is not returning -EFAULT if user pointer is NULL. This
