Replace existing resource handling in the driver with managed device resources, this ensures more consistent error values and simplifies error handling paths: kzalloc -> devm_kzalloc gpio_request_one -> devm_gpio_request_one input_allocate_polled_device -> devm_input_allocate_polled_device Signed-off-by:

Managed resources are becoming more and more popular in drivers. Let's implement managed polled input devices, to complement managed regular input devices. Similarly to managed regular input devices only one new call devm_input_allocate_polled_device() is added and the rest of APIs is modified to work with both managed and non-managed devices.

Polled device's attributes controlling polling rate and whether polling is enabled are attached to input device. We should have device core instantiate them for us, so that they are created by the time new device notification is sent to userspace, instead of doing it ourselves afterwards. Tested-by:

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 b534422b (Input: ad7877 - switch to using threaded IRQ) for code complexity reasons. It may be better to revert that commit instead.

We put this workaround in 2008 and the offending userspace has been fixed up long time ago; the link in the message is no longer valid either, so it is time to retire it. Reviewed-by:

The w90p910_ts touchscreen driver is heavily architecture dependent, so there is no point in letting it be built on other architectures than it was written for. All other W90P910/W90X900 drivers already have that dependency, so it makes things more consistent and configuration easier. Signed-off-by:

Addresses issues related to when a second finger enters or leaves the field, causing the cursor to jump or the page to scroll unexpectedly; now, we discard any movement change that happens at the exact moment we detect a change in the number of fingers touching the trackpad. This doesn't completely resolve the issue but does greatly mitigate it. Signed-off-by:
