In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu/gfx6: fix firmware leak on teardown

The firmware requested in gfx_v6_0_init_microcode() is not released when the GFX block is torn down, leaking the firmware resources.

Add gfx_v6_0_free_microcode() and call it from gfx_v6_0_sw_fini() to release the PFP, ME, CE and RLC firmware.

(cherry picked from commit 386e81346f95ab0be5a82c5535de932e7a456924)
