2023-07-08Input: ektf2127 - simplify with dev_err_probe()Krzysztof Kozlowski1-6/+2
Common pattern of handling deferred probe can be simplified with dev_err_probe(). Less code and also it prints the error value.

2023-05-17Input: Switch i2c drivers back to use .probe()Uwe Kleine-König1-1/+1
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

2023-01-10input: ektf2127 - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()Jonathan Cameron1-5/+5
SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection against unused function warnings. The new combination of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the __maybe_unused markings.

2022-12-03Input: ektf2127 - Convert to i2c's .probe_new()Uwe Kleine-König1-3/+2
The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted.

2020-11-09Input: ektf2127 - add support for eKTF2132 touchscreenJonathan Neuschäfer1-1/+31
The eKTF2132 is a touchscreen controller found, for example, in the Kobo Aura ebook reader. It is similar to the ektf2127, but it uses a different packet type to report touch events.

2016-10-04Input: ektf2127 - mark PM functions as __maybe_unusedArnd Bergmann1-2/+2
The newly added ektf2127 driver uses the SIMPLE_DEV_PM_OPS macro to conditionally refer to the resume/suspend functions, which causes a warning when CONFIG_PM_SLEEP is disabled: drivers/input/touchscreen/ektf2127.c:168:12: error: 'ektf2127_resume' defined but not used [-Werror=unused-function] drivers/input/touchscreen/ektf2127.c:156:12: error: 'ektf2127_suspend' defined but not used [-Werror=unused-function] We could either put these functions inside of an #ifdef or add __maybe_unused annotations. This uses the second approach, which is generally more foolproof.
