Tetsuo Handa 5d53797ce7 Input: iforce - invert valid length check when fetching device IDs ... commit b8ebf250997c5fb253582f42bfe98673801ebebd upstream. syzbot is reporting uninitialized value at iforce_init_device() [1], for commit 6ac0aec6b0 ("Input: iforce - allow callers supply data buffer when fetching device IDs") is checking that valid length is shorter than bytes to read. Since iforce_get_id_packet() stores valid length when returning 0, the caller needs to check that valid length is longer than or equals to bytes to read.
