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: egalax_ts_serial - fix potential NULL dereference on error

We didn't check input_allocate_device() for failures so it could lead to a NULL deref. Fixes: 6b0f8f9c52ef ('Input: add eGalaxTouch serial touchscreen driver') Signed-off-by: Dan Carpenter Signed-off-by: Dmitry Torokhov

Input: add eGalaxTouch serial touchscreen driver

2015-12-16T19:31:33Z

There are two EETI touchscreen drivers in the kernel (eeti_ts and egalax_ts) but both are for I2C-connected panels. This is for a different, serial and not multi-touch touchscreen panel.
