| | | | | | | One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct gpio_keys_polled_dev { ... struct gpio_keys_button_data data[0]; }; size = sizeof(struct gpio_keys_polled_dev) + count * sizeof(struct gpio_keys_button_data); instance = devm_kzalloc(dev, size, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, data, count), GFP_KERNEL); Notice that, in this case, variable size is not necessary, hence it is removed. This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R.

On some Lenovo t480s, this results in the touchpad not being detected as a clickpad, and on the Lenovo P52, this results in a failure while fetching the resolution through I2C. We need to imitate the Windows behavior: fetch the data under PS/2, and limit the querries under I2C. This patch prepares this by exporting the info from PS/2.

TL;DR: the P52 and the t480s from Lenovo can't rely on I2C to fetch the information, so we need it from PS/2.

On some of these new IC, the I2C part doesn't have all of the information available. We need to be able to forward the touchpad parameters from PS/2 and thus, we need those new optional properties.

| | | | | | | | | | | | | | Looks like the new generation of Lenovo machine also need to be added to the PnPID whitelist. This is definitively not going to scale, as there is nothing that tells us currently if a touchpad supports a true physical middle button. Consider that all new touchpads that are not clickpads (so matching ETP_NEW_IC_SMBUS_HOST_NOTIFY) are handling 3 physical buttons.

In such cases, the interrupt will never occur again after resume, hence the touch screen appears dead. To fix this, check for the assertion of the attn gpio, and read form the controller once in the resume path to read the hardware status and to arm the IRQ again. Introduce a mutex to guard eeti_ts_read() against parallel invocations from different contexts.
