2024-04-30Input: ff-core - prefer struct_size over open coded arithmeticErick Archer1-3/+4
This is an effort to get rid of all multiplications from allocation functions in order to prevent integer overflows [1][2]. As the "ff" variable is a pointer to "struct ff_device" and this structure ends in a flexible array: struct ff_device { [...] struct file *effect_owners[] __counted_by(max_effects); }; the preferred way in the kernel is to use the struct_size() helper to do the arithmetic instead of the calculation "size + count * size" in the kzalloc() function. The struct_size() helper returns SIZE_MAX on overflow. So, refactor the comparison to take advantage of this. This way, the code is more readable and safer. This code was detected with the help of Coccinelle, and audited and modified manually.

2024-01-20dt-bindings: input: touchscreen: goodix: clarify irq-gpios misleading textLuca Ceresoli1-2/+3
The irq-gpios description misleading, apparently saying that driving the IRQ GPIO resets the device, which is even more puzzling as there is a reset GPIO as well. In reality the IRQ pin can be driven during the reset sequence to configure the client address, as it becomes clear after checking both the datasheet and the driver code. Improve the text to clarify that. Also rephrase to remove reference to the driver, which is not appropriate in the bindings.

2024-01-20dt-bindings: input: silead,gsl1680: do not override firmware-name $refKrzysztof Kozlowski1-1/+1
dtschema package defines firmware-name as string-array, so individual bindings should not make it a string but instead just narrow the number of expected firmware file names.

2024-01-20Input: remove usage of the deprecated ida_simple_xx() APIChristophe JAILLET1-8/+6
ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_range() is inclusive. So a -1 has been added when needed.

While input core can work with input->phys set to NULL userspace might depend on it, so better fail probing if allocation fails. The system must be in a pretty bad shape for it to happen anyway.
