Hanging on [drm] Initialized i915 1.6.0 20201103 for 0000:00:02.0 on minor 0

With the kernel v5.15.129 and using the i915 driver as built-in module on my hardware it hang the kernel load on the follow log:

[drm] Initialized i915 1.6.0 20201103 for 0000:00:02.0 on minor 0

Making some debug by print I reach the i915_hwmon_register which is the function that does not return.
My hardware is an Intel(R) Atom(TM) x5-Z8350

Interestingly, this did not occur in v5.10...

on the Kernel v6.1 I saw that was introduced a check:

https://github.com/intel/linux-intel-lts/blob/e13503e423ba533c6c4304fd242e8f001005706d/drivers/gpu/drm/i915/i915_hwmon.c#L791C2-L792C21

void i915_hwmon_register(struct drm_i915_private *i915)
{
...
        /* hwmon is available only for dGfx */
	if (!IS_DGFX(i915))

this should not be checked also for the v5.15.129?

If I add the follow on the code from v5.15.129:

        /* hwmon is available only for dGfx */
	if (!IS_DGFX(i915))
               return;

It works, so now I'm thinking why without this on the v5.10 works...

Well, I take back what I said, I got the latest update of v5.10 the 5.10.184 and the issue is the same...
