The comment in dma_buf_llseek() referenced a "SEEK_END(0), SEEK_CUR(0) pattern", but the implementation does not support SEEK_CUR - it only handles SEEK_END and SEEK_SET, returning -EINVAL for anything else.
Replace SEEK_CUR with SEEK_SET in the comment so that it accurately describes the supported idiomatic pattern.
