Input: touchscreen - use sizeof(*pointer) instead of sizeof(type)

2024-06-09T21:38:38Z

It is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter). The refactoring is mostly trivial except for "usbtouchscreen.c" file. Here, in the "mtouch_alloc" and "nexio_alloc" functions, it is necessary to use a variable with a predefined type instead of the "usbtouch->priv" variable (void * type). This way, the "sizeof" operator can now know the correct size. Moreover, we need to set the "usbtouch->priv" pointer after the memory allocation since now the "kmalloc" return value is not assigned directly. This patch has no effect on runtime behavior.

Input: move from strlcpy with unused retval to strscpy

2022-08-18T22:44:08Z

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

Input: wacom_w8001 - allocate additional space for 'phys'

2019-08-20T19:03:46Z

GCC warns that the output of our call to 'snprintf' in 'w8001_connect' may be truncated since both 'serio->phys' and 'w8001->phys' are 32 bytes in length. Increase the amount of space allocated for the latter to compensate. Signed-off-by: Jason Gerecke Signed-off-by: Dmitry Torokhov

Input: wacom_w8001 - constify serio_device_id

2017-08-19T00:15:41Z

serio_device_id are not supposed to change at runtime. All functions working with serio_device_id provided by work with const serio_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav Signed-off-by: Dmitry Torokhov

Revert "Input: wacom_w8001 - drop use of ABS_MT_TOOL_TYPE"

2016-07-14T16:33:41Z

This reverts commit 5f7e5445a2de848c66d2d80ba5479197e8287c33 because removal of input_mt_report_slot_state() means we no longer generate tracking IDs for the reported contacts. Cc: stable@vger.kernel.org Acked-by: Peter Hutterer Acked-by: Ping Cheng
