Subject: [PATCH 1/3] Input: apbps2: Delete an error message for a failed memory allocation in apbps2_of_probe()

From: Markus Elfring <[email protected]>

Omit an extra message for a memory allocation failure in this function.

This issue was detected by using the Coccinelle software.

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
