[PATCH 1/2] drm/amdgpu: fix amdgpu_irq_put call trace in jpeg_v4_0_hw_fini

[Zhang, Hawking]

[AMD Official Use Only - General]

Shall we consider creating amdgpu_vcn_ras_late_init as a common helper for interrupt enablement, like other IP blocks. This also reduces further effort when RAS feature is introduced in new version of vcn/jpeg

Regards,
Hawking
