Subject: [PATCH] drm/panthor: Fix error code in panthor_gpu_init()
This code accidentally returns zero/success on error because of a typo.
It should be "irq" instead of "ret". The other thing is that if
platform_get_irq_byname() were to return zero then the error code would
be cmplicated. Fortunately, it does not so we can just change <= to
< 0.
Fixes: 5cd894e258c4 ("drm/panthor: Add the GPU logical block")
