* drm/amdgpu: Clean the functions pointer set as NULLSunil Khatri2024-10-221-1/+0
| | | | | | | | | | | We dont need to set the functions to NULL which arent needed as global structure members are by default set to zero or NULL for pointers.

* drm/amd: Don't initialize ISP hardware without FWMario Limonciello2024-06-271-2/+2
| | | | | | | | | | | | | | | | Although designs may contain an ISP IP block, the camera might be a USB camera. Because of this the ISP firmware is considered optional from amdgpu. However if the firmware doesn't get loaded the hardware should not be initialized. Adjust the return code for early init to ensure the IP block doesn't go through the other init and fini sequences. Also decrease the message about firmware load failure to debug so it's not as alarming to users.

| | | | | | | | | | | | | | | | | | | | | | | | | | snprintf can truncate the output fw filename if the isp ucode_prefix exceeds 29 characters.
