2013-09-04CHROMIUM: hid-logitech-wtp: Fixed button issue on WTPDennis Kempin1-4/+9
The buttons on WTP do not work when a finger is present on the touchpad. This is caused by the raw event overriding the button state. WTP does not send button states in the raw events. This CL adds a new event format to distinguish between those two cases.

2013-09-04hid-logitech-wtp: refactoring for extensibilityDennis Kempin2-278/+401
Refactored the driver to allow for future devices to be added. - Changed the initialization procedure to support multiple hidpp features. Each feature has methods attached to it, that take care of init, polling and parsing of events. - During init, the driver selects the first available feature that is supported (Currently only TouchPadRawXY is supported). - All device-specific branches are happening during the init method. e.q. don't send T651 to raw mode. - TouchpadRawXY allows two different event formats. Raw or attached to the end of the mouse events. The init method decides which one to use. - The data structures now reflect the data required to generate the output, no longer the data available from the device. - Reordered and renamed to reflect feature-specific code and generic code. BUG=chromium:240850 TEST=manually test with all 3 previously supported touchpads.

This touchpad is similar to the T650, but has a few notable differences: - It connects via Bluetooth as opposed to the Unifying Receiver - The raw data reports are in a unique format appended to normal mouse reports. The mouse reports must be ignored. Putting this pad into raw data mode will work as the T650 does, but Nestor Lopez Casado of Logitech advises against as that mode as it's not officially supported.

2013-08-23drivers/platform/olpc/olpc-ec.c: initialise earlierDaniel Drake1-1/+1
Being a low-level component, various drivers (e.g. olpc-battery) assume that it is ok to communicate with the OLPC Embedded Controller during probe. Therefore the OLPC EC driver must be initialised before other drivers try to use it. This was the case until it was recently moved out of arch/x86 and restructured around commits ac2504151f5a ("Platform: OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86: OLPC: switch over to using new EC driver on x86"). Use arch_initcall so that olpc-ec is readied earlier, matching the previous behaviour. Fixes a regression introduced in Linux-3.6 where various drivers such as olpc-battery and olpc-xo1-sci failed to load due to an inability to communicate with the EC. The user-visible effect was a lack of battery monitoring, missing ebook/lid switch input devices, etc. Signed-off-by: Daniel Drake <dsd@laptop.org> Cc: Andres Salomon <dilinger@queued.net> Cc: Paul Fox <pgf@laptop.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2013-08-22ipv4: expose IPV4_DEVCONFstephen hemminger2-33/+35
IP sends device configuration (see inet_fill_link_af) as an array in the netlink information, but the indices in that array are not exposed to userspace through any current santized header file. It was available back in 2.6.32 (in /usr/include/linux/sysctl.h) but was broken by: commit 02291680ffba92e5b5865bc0c5e7d1f3056b80ec Author: Eric W. Biederman <ebiederm@xmission.com> Date: Sun Feb 14 03:25:51 2010 +0000 net ipv4: Decouple ipv4 interface parameters from binary sysctl numbers Eric was solving the sysctl problem but then the indices were re-exposed by a later addition of devconf support for IPV4 commit 9f0f7272ac9506f4c8c05cc597b7e376b0b9f3e4 Author: Thomas Graf <tgraf@infradead.org> Date: Tue Nov 16 04:32:48 2010 +0000 ipv4: AF_INET link address family Putting them in /usr/include/linux/ip.h seemed the logical match for the DEVCONF_ definitions for IPV6 in /usr/include/linux/ip6.h Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S.

2013-08-22ipv6: handle Redirect ICMP Message with no Redirected Header optionDuan Jiong3-1/+26
rfc 4861 says the Redirected Header option is optional, so the kernel should not drop the Redirect Message that has no Redirected Header option. In this patch, the function ip6_redirect_no_header() is introduced to deal with that condition.

2013-08-22be2net: fix disabling TX in be_close()Sathya Perla1-1/+1
commit fba875591 ("disable TX in be_close()") disabled TX in be_close() to protect be_xmit() from touching freed up queues in the AER recovery flow. But, TX must be disabled *before* cleaning up TX completions in the close() path, not after. This allows be_tx_compl_clean() to free up all TX-req skbs that were notified to the HW.

This reverts commit 58ad436fcf49810aa006016107f494c9ac9013db. It turns out that the change introduced a potential deadlock by causing a locking dependency with netlink's cb_mutex. I can't seem to find a way to resolve this without doing major changes to the locking, so revert this.
