Series Input: serio - use sizeof(*pointer) instead of sizeof(type) | expand

Commit Message

Erick Archer June 7, 2024, 5:04 p.m. UTC 
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). This patch has no effect
on runtime behavior.
