Input: elantech - fix absolute mode setting on some ASUS laptops
On ASUS TP500LN and X750JN, the touchpad absolute mode is reset each time set_rate is done. In order to fix this, we will verify the firmware version, and if it matches the one in those laptops, the set_rate function is overloaded with a function elantech_set_rate_restore_reg_07 that performs the set_rate with the original function, followed by a restore of reg_07 (the register that sets the absolute mode on elantech v4 hardware). Also the ASUS TP500LN and X750JN firmware version, capabilities, and button constellation is added to elantech.c Cc: stable@vger.kernel.org Reported-and-tested-by: George Moutsopoulos <gmoutso@yahoo.co.uk> Signed-off-by: Ulrik De Bie <ulrik.debie-os@e2big.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
