In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix svm_migrate_fini warning Device manager releases device-specific resources when a driver disconnects from a device, devm_memunmap_pages and devm_release_mem_region calls in svm_migrate_fini are redundant. It causes below warning trace after patch "drm/amdgpu: Split amdgpu_device_fini into early and late", so remove function svm_migrate_fini.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amdkfd: corrige la advertencia de svm_migrate_fini. El administrador de dispositivos libera recursos específicos del dispositivo cuando un controlador se desconecta de un dispositivo, las llamadas a devm_memunmap_pages y devm_release_mem_region en svm_migrate_fini son redundantes. Provoca el siguiente seguimiento de advertencia después del parche "drm/amdgpu: dividir amdgpu_device_fini en temprano y tarde", por lo tanto, elimine la función svm_migrate_fini.
