Input: mousedev - fix implicit conversion warning

2017-07-25T20:54:31Z

Clang warns: drivers/input/mousedev.c:653:63: error: implicit conversion from 'int' to 'signed char' changes value from 200 to -56 [-Wconstant-conversion] client->ps2[1] = 0x60; client->ps2[2] = 3; client->ps2[3] = 200; ~ ^~~ As the PS2 data is really a stream of bytes, let's switch to using u8 type for it, which silences this warning.

input: utilize new cdev_device_add helper function

2017-03-21T05:44:32Z

Replace the open coded registration of the cdev and dev with the new device_add_cdev() helper in evdev, joydev and mousedev. The helper replaces a common pattern by taking the proper reference against the parent device and adding both the cdev and the device.

Input: mousedev - fix race when creating mixed device

2014-03-29T21:44:23Z

We should not be using static variable mousedev_mix in methods that can be called before that singleton gets assigned. While at it let's add open and close methods to mousedev structure so that we do not need to test if we are dealing with multiplexor or normal device and simply call appropriate method directly.

Input: mousedev - move /dev/input/mice to the correct minor

2012-11-19T07:15:16Z

When doing conversion to dynamic input numbers I inadvertently moved /dev/input/mice from c,13,63 to c,13,31. We need to fix this so that setups with statically populated /dev continue working. Tested-by: Krzysztof Mazur Tested-by: Pavel Machek Signed-off-by: Dmitry Torokhov

Input: fix use-after-free introduced with dynamic minor changes

2012-10-22T05:50:37Z

Commit 7f8d4cad1e4e ("Input: extend the number of event (and other) devices") made evdev, joydev and mousedev to embed struct cdev into their respective structures representing input devices. Unfortunately character device structure may outlive the parent structure unless we do not set it up as parent of character device so that it will stay pinned until character device is freed. Also, now that parent structure is pinned while character device exists we do not need to pin and unpin it every time user opens or closes it.

Input: extend the number of event (and other) devices

2012-10-08T16:37:55Z

Extend the amount of character devices, such as eventX, mouseX and jsX, from a hard limit of 32 per input handler to about 1024 shared across all handlers. To be compatible with legacy installations input handlers will start creating char devices with minors in their legacy range, however once legacy range is exhausted they will start allocating minors from the dynamic range 256-1024.

Input: mousedev - mark mousedev interfaces as non-seekable

2012-10-08T16:37:50Z

Seeking does not make sense for mousedev, so let's use nonseekable_open() to mark its devices as non-seekable. Reviewed-by: David Herrmann Signed-off-by: Dmitry Torokhov

Input: mousedev - rename mixdev_open to opened_by_mixdev

2012-10-08T16:37:45Z

Do the rename to make the logic more clear and also change it to bool while at it. Reviewed-by: David Herrmann Signed-off-by: Dmitry Torokhov
