drm/amdgpu/psp: move PSP memory alloc from hw_init to sw_init

2022-06-09T08:25:24Z

[ Upstream commit b95b5391684b39695887afb4a13cccee7820f5d6 ] Memory allocations should be done in sw_init. hw_init should just be hardware programming needed to initialize the IP block. This is how most other IP blocks work. Move the GPU memory allocations from psp hw_init to psp sw_init and move the memory free to sw_fini. This also fixes a potential GPU memory leak if psp hw_init fails. Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin
