Input: msc5000_ts - remove the driver

2024-07-16T01:12:23Z

MCS-5000 belongs to the 1st generation of Melfas chips, manufactured in 2000-2007. The driver relies on custom platform data (no DT support) and there never were any users of this driver in the mainline kernel. The commit adding the driver mentioned that the driver was tested on S3C6410 NCP board (with Samsung S3C6410 SoC) but the touchscreen device was never added to the board file. This board was removed in v6.3 in commit 743c8fbb90ca ("ARM: s3c: remove most s3c64xx board support"). Remove the driver since there are no users.

Input: drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-05-13T22:43:19Z

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

Input: Switch i2c drivers back to use .probe()

2023-05-17T16:59:11Z

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.

Input: mcs5000_ts - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2023-01-10T04:25:26Z

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.

Input: mcs5000_ts - Convert to i2c's .probe_new()

2022-12-02T22:53:46Z

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20221118224540.619276-250-uwe@kleine-koenig.org Signed-off-by: Dmitry Torokhov

Input: touchscreen - drop unnecessary calls to input_set_drvdata

2017-01-23T01:22:31Z

Since there is no call to dev_get_drvdata() or input_get_drvdata(), the call to input_set_drvdata() is unnecessary and can be dropped. Signed-off-by: Guenter Roeck Signed-off-by: Dmitry Torokhov

Input: mcs5000_ts - remove ifdef around power management methods

2014-07-31T05:52:56Z

We can annonate the suspend/resume functions with '__maybe_unused' and get rid of the ifdef, which makes the code smaller and simpler. Signed-off-by: Fabio Estevam Signed-off-by: Dmitry Torokhov

Input: mcs5000_ts - protect PM functions with CONFIG_PM_SLEEP

2014-07-31T05:52:55Z

When a kernel has CONFIG_PM=y and CONFIG_PM_SLEEP=n the following warnings are seen: drivers/input/touchscreen/mcs5000_ts.c:252:12: warning: 'mcs5000_ts_suspend' defined but not used [-Wunused-function] static int mcs5000_ts_suspend(struct device *dev) ^ drivers/input/touchscreen/mcs5000_ts.c:262:12: warning: 'mcs5000_ts_resume' defined but not used [-Wunused-function] static int mcs5000_ts_resume(struct device *dev) Protect the suspend/resume functions with CONFIG_PM_SLEEP in order to fix these build warnings.
