[greybus-dev] Re: [PATCH v3] staging: greybus: uart: return tty_alloc_driver() errors

gb_tty_init() maps any tty_alloc_driver() failure to -ENOMEM. tty_alloc_driver() currently always returns -ENOMEM on failure, so this does not change behavior in practice. However, returning PTR_ERR(gb_tty_driver) is more correct and consistent with kernel conventions, preserving any future error codes the function might return.
