En el kernel de Linux se ha resuelto la siguiente vulnerabilidad:

drm/amdgpu/gfx6: corrige la fuga de firmware al desmontar

El firmware solicitado en gfx_v6_0_init_microcode() no se libera cuando el bloque GFX se desmonta, lo que provoca una fuga de recursos de firmware.

Añade gfx_v6_0_free_microcode() y la invoca desde gfx_v6_0_sw_fini() para liberar el firmware de PFP, ME, CE y RLC.

(cherry picked from commit 386e81346f95ab0be5a82c5535de932e7a456924)
