Input: do not use WARN() in input_alloc_absinfo()

2018-09-15T07:45:30Z

[ Upstream commit 100294cee9a98bfd4d6cb2d1c8a8aef0e959b0c4 ] Some of fuzzers set panic_on_warn=1 so that they can handle WARN()ings the same way they handle full-blown kernel crashes. We used WARN() in input_alloc_absinfo() to get a better idea where memory allocation failed, but since then kmalloc() and friends started dumping call stack on memory allocation failures anyway, so we are not getting anything extra from WARN(). Because of the above, let's replace WARN with dev_err(). We use dev_err() instead of simply removing message and relying on kcalloc() to give us stack dump so that we'd know the instance of hardware device to which we were trying to attach input device.

Input: allow matching device IDs on property bits

2017-10-19T23:54:49Z

Let's allow matching input devices on their property bits, both in-kernel and when generating module aliases. Tested-by: Roderick Colenbrander Signed-off-by: Dmitry Torokhov

Input: factor out and export input_device_id matching code

2017-10-19T23:53:34Z

Factor out and export input_match_device_id() so that modules may use it. It will be needed by joydev to blacklist accelerometers in composite devices. Tested-by: Roderick Colenbrander Signed-off-by: Dmitry Torokhov

Input: constify attribute_group structures

2017-07-12T21:18:26Z

attribute_groups are not supposed to change at runtime. All functions working with attribute_groups provided by work with const attribute_group. So mark the non-const structs as const.

Input: switch to using sizeof(*type) when allocating memory

2017-05-10T21:39:34Z

Instead of specifying type explicitly, derive it from the type of pointer when allocating memory, which is considered safer practice. Signed-off-by: Markus Elfring Signed-off-by: Dmitry Torokhov

Input: use seq_puts() in input_devices_seq_show()

2017-05-10T21:39:34Z

Use seq_puts() when printing a string which does not contain a data format specification. Signed-off-by: Markus Elfring Signed-off-by: Dmitry Torokhov

Input: use seq_putc() in input_seq_print_bitmap()

2017-05-10T21:39:33Z

Switch to using seq_putc() when printing a single character '0'. Signed-off-by: Markus Elfring Signed-off-by: Dmitry Torokhov

Input: refuse to register absolute devices without absinfo

2017-02-01T18:33:21Z

If device is supposed to send absolute events (i.e. EV_ABS bit is set in dev->evbit) but dev->absinfo is not allocated, then the driver has done something wrong, and we should not register such device. Otherwise we'll crash later, when driver tries to send absolute event. Reviewed-by: Benjamin Tissoires Acked-by: Jiri Kosina Signed-off-by: Dmitry Torokhov

Input: constify device_type structures

2017-01-24T20:38:49Z

Declare device_type structures as const as they are only stored in the type field of a device structure. This field is of type const, so add const to declaration of device_type structures.
