2020-07-06Input: elantech - remove redundant assignments to variable errorColin Ian King1-3/+3
The variable error is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.

2020-05-18Input: iqs269a - add missing I2C dependencyJeff LaBundy1-0/+1
If CONFIG_INPUT_IQS269A is selected yet CONFIG_I2C is not, the build fails. To solve this problem, add I2C as a dependency.

2020-05-17Input: elants - refactor elants_i2c_execute_command()Michał Mirosław1-101/+99
Apply some DRY-ing to elants_i2c_execute_command() callers. This pulls polling and error printk()s into a single function.

2020-05-17Input: elants - override touchscreen info with DT propertiesMichał Mirosław1-2/+5
Allow overriding of information from hardware and support additional common DT properties like axis inversion. This is required for eg. Nexus 7 and TF300T where the programmed values in firmware differ from reality.

2020-05-17Input: elants - remove unused axesMichał Mirosław1-18/+8
Driver only ever reports MT events and input_mt_init_slots() sets up emulated axes already. Clear the capabilities not generated directly and move MT axes setup, so they are visible by input_mt_init_slots().
