Input: ad7877 - use device core to create driver-specific device attributes

2023-09-06T21:23:47+00:00

Instead of creating driver-specific device attributes with devm_device_add_group() have device core do this by setting up dev_groups pointer in the driver structure.

Input: ad7877 - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2023-01-10T04:25:23+00:00

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: ad7877 - use new structure for SPI transfer delays

2020-12-11T07:39:15+00:00

In a recent change to the SPI subsystem [1], a new `delay` struct was added to replace the `delay_usecs`. This change replaces the current `delay_usecs` with `delay` for this driver. The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure that both `delay_usecs` & `delay` are used (in this order to preserve backwards compatibility).

Input: ad7877 - use managed resource allocations

2018-01-23T00:25:53+00:00

Use managed resource allocations to simplify error handling during probing failure and module exiting. With this all the goto labels in the probe function together with the cleanups in the remove function are unnecessary, therefore removed. Signed-off-by: Andi Shyti Signed-off-by: Dmitry Torokhov

Input: ads7877 - remove bitrotted comment

2014-05-14T23:39:47+00:00

While searching for users of spi_async() I found a reference in the ad7877 driver to using it to initiate data transfer from the interrupt handler. However there is no code for this, instead the interrupt handler is a threaded handler and uses spi_sync() instead. Remove the bitrotted comment, though in actual fact the use case mentioned is a great use for spi_async() since it would cut down on latency handling the interrupt by saving us a context switch before we start SPI. This was previously implemented, it was removed in commit b534422b2d11 (Input: ad7877 - switch to using threaded IRQ) for code complexity reasons. It may be better to revert that commit instead.

Input: delete non-required instances of include

2014-01-07T07:23:57+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Signed-off-by: Paul Gortmaker Signed-off-by: Dmitry Torokhov
