It is no need to check the packet[0] for sanity check when doing
elantech_packet_check_v4() function for fw_version = 0x470f01 touchpad.

Input: alps - only Dell laptops have separate button bits for v2 dualpoint sticks

2015-08-03T21:11:47+00:00

It turns out that only Dell laptops have the separate button bits for
v2 dualpoint sticks and that commit 92bac83dd79e ("Input: alps - non
interleaved V2 dualpoint has separate stick button bits") causes
regressions on Toshiba laptops.

This commit adds a check for Dell laptops to the code for handling these
extra button bits, fixing this regression.

This patch has been tested on a Dell Latitude D620 to make sure that it
does not reintroduce the original problem.

Input: axp20x-pek - add module alias

Add a proper module alias so the driver can be autoloaded when the
parent axp20x mfd driver registers its cells.

Possibly off by one.  >= 6.

Let's change the upper value to ARRAY_SIZE(tgfx_buttons) to ensure we do
not reach past the end of the array.

Revert "Input: zforce - don't overwrite the stack"

2015-07-28T17:25:03+00:00

This reverts commit 7d01cd261c76f95913c81554a751968a1d282d3a because
with given FRAME_MAXSIZE of 257 the check will never trigger and it
causes warnings from GCC (with -Wtype-limits). Also the check was
incorrect as it was not accounting for the already read 2 bytes of data
stored in the buffer.

Input: bcm5974 - add support for the 2015 Macbook Pro

2015-07-27T22:43:47+00:00

Add support for the MacBookPro12,1 model. This patch needs to be
applied together with the accompanied HID patch, as usual.

Input: bcm5974 - prepare for a new trackpad generation

2015-07-27T22:43:45+00:00

With the advent of the Macbook Pro 12, we see a new generation of
trackpads, capable of force sensoring and haptic feedback.

This patch prepares for the new device by adding configuration data
for the code paths that would otherwise look different.
