Axel Lin	1b92c1cf6b	Input: convert I2C drivers to use module_i2c_driver() ... This patch converts the drivers in drivers/input/* to use the module_i2c_driver() macro which makes the code smaller and a bit simpler.

Jiejing Zhang	c7b4a5d58b	Input: mpr121 - improve sensibility of touch key ... The Quick Charge bit in Electrode conf register should be set in init function. This bit was missed in chip's document, which may cause touch controller charge too slow to generate an interrupt. Also, adjust the default vlaue of touch and release threshold to make touch key more sensitive, this fix touch may not sensitive after setup with plastic case.
