Forward declarations make the code larger and rewrites harder. Harder as they are often omitted from global changes. Remove forward declarations which are not really needed, i.e. the definition of the function is before its first use. Cc: linuxppc-dev@lists.ozlabs.org Reviewed-by:

ptychar was not const, so mark it as such. And move this variable to the only place where it's used. Signed-off-by:

Now that noone checks the return value, switch the return type of tty_unregister_driver to void. We can do that as we always return zero. Generally, drivers are not allowed to call tty_unregister_driver while there are open devices. Signed-off-by:

These drivers check tty_unregister_driver return value. But they don't handle a failure correctly (they free the driver in any case). So stop checking tty_unregister_driver return value and remove also the prints. In the next patch, tty_unregister_driver's return type will be switched to void.

We already do tty_port_link_device in rs_init, so we don't need to reassign a port to tty->port. It would be too late in tty::ops::open anyway. Cc: Chris Zankel <chris@zankel.net> Cc: Max Filippov <jcmvbkbc@gmail.com> Cc: linux-xtensa@linux-xtensa.org Acked-by:

There is no need to print the information during module load. Neither to print some artificial version. So drop these strings and a print. Cc: Chris Zankel <chris@zankel.net> Cc: Max Filippov <jcmvbkbc@gmail.com> Cc: linux-xtensa@linux-xtensa.org Acked-by:

tty_wakeup is safe to be called from all contexts. No need to schedule a tasklet for that. Let us call it directly like in other drivers. And delete the tasklet completely.

nci_uart_register returns -EINVAL immediately when nu->ops.recv is not set. So the same 'if' later never triggers so nci_uart_default_recv is never used. Drop it. Cc: "David S. Miller" <davem@davemloft.net> Cc: Jakub Kicinski <kuba@kernel.org> Cc: netdev@vger.kernel.org Signed-off-by:

There is noone setting nci_uart_ops::recv_buf, so the default one (nci_uart_default_recv_buf) is always used. So drop this hook, move nci_uart_default_recv_buf before the use in nci_uart_tty_receive and remove unused parameter flags. Cc: "David S.

register_ldisc only calls tty_register_ldisc. Inline register_ldisc into the only caller of register_ldisc, i.e. caif_ser_init. Now, caif_ser_init is symmetric to caif_ser_exit in this regard.

The caller expects from the others (pfc_config and multi_config) to return standard error values. So do the same for simple_config too. We invert the if condition to handle the error case. Signed-off-by:

This really eliminates multiplications from the assembly. I would have thought they are optimized by inlining ktime_set, but not on x86_64 with gcc 10. Signed-off-by:

Set tty_ldisc_ops::owner to THIS_MODULE. This has no effect currently as n_tty cannot be built as a module. If someone ever tries to modularize tty, we wouldn't manage module's reference count as in other ldiscs. So fix this just in case. Signed-off-by:

First, it is never checked. Second, use of it as a debugging aid is at least questionable. With the current tools, I don't think anyone used this kind of thing for debugging purposes for years. On the top of that, e.g. serdev does not set this field of tty_ldisc_ops at all. So get rid of this legacy. Signed-off-by:

While the driver is still marked as maintained in MAINTAINERS, Comtrol does not really care about this ancient driver. They are still manufacturing serial devices, but those are controlled only by out-of-tree drivers. Comtrol didn't answer my pings, so this driver is apparently unmaintained. Aside from that, the driver was untouched for years, only whole-tree changes happened during the past years. The driver needs much more care, so drop it for now. If someone steps up to reintroduce it, they need to clean it up first. Signed-off-by:

The Isicom driver was orphaned by commit d86b3001 (MAINTAINERS: orphan isicom) 10 years ago. Noone stepped up to take care of them and to fix all the issues the driver has. So it's time to drop the driver with all its traces. Signed-off-by:

The Cyclades driver was orphaned by commit d459883e (MAINTAINERS: remove two dead e-mail) 13 years ago. Noone stepped up to take care of them and to fix all the issues the driver has. On the top of that, there is no way to obtain the firmware for Z cards from the vendor as cyclades.com ceased to exist. So it's time to drop the driver with all its traces. Signed-off-by:

I cannot maintain this driver for years due to missing HW. Let's orphan the entry in MAINTAINERS. And likely drop the driver later as these devices are likely gone from this world. Mxser provides different (out-of-tree) drivers for their current devices. Signed-off-by:

No need to keep around the dentry pointer for the debugfs file if all it is used for is to remove it when we are wanting to clean up, as the pointer can be looked up directly from debugfs instead. This also removes pointless #ifdef CONFIG_DEBUG_FS brackets as the compiler is smart enough to handle this properly if debugfs is disabled without us having to worry about it.
