[ Upstream commit 4bb1ce2350a598502b23088b169e16b43d4bc639 ]
When console device is rebinded, console_setup() is called again. But marking it as __init means that function will be clear after boot is complete. If console device is binded again console_setup() is not found and error "Unable to handle kernel paging request at virtual address" is reported.
