The subject is wrong, nothing x86-specific here. Please use
"swiotlb: " as the prefix

Please avoid the overly long line.

I'd word this as:
/*
* If swiotlb_unencrypted_base is set, the bounce buffer memory will
* be remapped and cleared in swiotlb_update_mem_attributes.
*/

With the latest update swiotlb_init_io_tlb_mem will always return 0,
so no need for the return value change or error handling here.
