Subject: Input: serio - use sizeof(*pointer) instead of sizeof(type)
X-Git-Tag: v6.11-rc1~98^2^2~62
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=06b449d7f7c361dc15ea040966a46ed2c6508f3b;p=thirdparty%2Fkernel%2Flinux.git

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

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.
