For the record, what was added:
#include <linux/array_size.h> // for ARRAY_SIZE
#include <linux/bits.h>  // for GENMASKxx
#include <linux/dev_printk.h> // for dev_err_probe, dev_info
#include <linux/math.h>  // for DIV_ROUND_UP
#include <linux/mutex.h> // for struct mutex
#include <linux/types.h> // for uXX defitinions

Changelog:
v3: removed of.h/compiler_types.h
    added types.h
v2: https://lore.kernel.org/all/20251206132120.11059-1-rodrigo.gobbi.7@gmail.com/
v1: https://lore.kernel.org/all/20251009182636.187026-1-rodrigo.gobbi.7@gmail.com/

Tks and regards.
