staging: unisys: visorinput: Use struct_size() helper in kzalloc()

Browse source

Make use of the struct_size() helper instead of an open-coded version,
in order to avoid any potential type mistakes or integer overflows that,
in the worst scenario, could lead to heap overflows.

Also, address the following sparse warnings:
drivers/staging/unisys/visorinput/visorinput.c:409:27: warning: using sizeof on a flexible structure
