[PATCH] staging: r8188eu: Use the ARRAY_SIZE() macro
From: Fabio M. De Francesco
Date: Sat Apr 02 2022 - 12:34:53 EST
Use the ARRAY_SIZE() macro in places where there are open coded
calculations of the size of arrays.
ARRAY_SIZE(arr) makes sure that "arr" is an array, it's safer than
sizeof(arr) / sizeof(arr[0]), and improves readibility.
Detected with the help of Coccinelle.
