[v2,18/32] mfd: sec: change device_type to int

Commit Message

André Draszik March 28, 2025, 1:29 p.m. UTC

Now that sec-i2c doesn't match device type by pointer casting anymore,
we can switch the device type from unsigned long to int easily.

This saves a few bytes in struct sec_pmic_dev due to member alignment.
