2019-09-04tty: nozomi: Use dev_get_drvdataChuhong Yuan
Instead of using to_pci_dev + pci_get_drvdata, use dev_get_drvdata to make code simpler. Signed-off-by: Chuhong Yuan <hslester96@gmail.com> Link: https://lore.kernel.org/r/20190724131825.1875-1-hslester96@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-02-12tty/nozomi: use pci_iomap instead of ioremap_nocacheHugo Lefeuvre
Use pci_iomap instead of ioremap_nocache in nozomi_card_init(). This is a cleaner way to do PCI MMIO (performs additional checks) and allows to drop the manual call to pci_resource_start. pci_iomap relies on ioremap for MMIO and thus has uncached behavior.

2017-11-08tty: Remove redundant license textGreg Kroah-Hartman
Now that the SPDX tag is in all tty files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

2017-11-08tty: add SPDX identifiers to all remaining files in drivers/tty/Greg Kroah-Hartman
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/tty files files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2016-11-29tty: nozomi: avoid sprintf buffer overflowArnd Bergmann
Testing with a gcc-7 snapshot produced an internal compiler error for this file: drivers/tty/nozomi.c: In function 'receive_flow_control': drivers/tty/nozomi.c:919:12: internal compiler error: in get_substring_ranges_for_loc, at input.c:1388 static int receive_flow_control(struct nozomi *dc) I've reported this at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78569 but also noticed that the code line contains a stack overflow, as it prints a string into a slightly shorter fixed-length 'tmp' variable. A lot of the code here is unnecessary and can be expressed in a simpler way, relying on the fact that removing the 'DEBUG' macro will also get rid of all pr_debug() calls. This change should not change any of the output but avoids both the stack overflow and the gcc crash. The stack overflow will not happen unless a module load parameter is also set to enable the debug messages.

2016-02-06tty: nozomi: avoid a harmless gcc warningArnd Bergmann
The nozomi wireless data driver has its own helper function to transfer data from a FIFO, doing an extra byte swap on big-endian architectures, presumably to bring the data back into byte-serial order after readw() or readl() perform their implicit byteswap. This helper function is used in the receive_data() function to first read the length into a 32-bit variable, which causes a compile-time warning: drivers/tty/nozomi.c: In function 'receive_data': drivers/tty/nozomi.c:857:9: warning: 'size' may be used uninitialized in this function [-Wmaybe-uninitialized] The problem is that gcc is unsure whether the data was actually read or not. We know that it is at this point, so we can replace it with a single readl() to shut up that warning. I am leaving the byteswap in there, to preserve the existing behavior, even though this seems fishy: Reading the length of the data into a cpu-endian variable should normally not use a second byteswap on big-endian systems, unless the hardware is aware of the CPU endianess. There appears to be a lot more confusion about endianess in this driver, so it probably has not worked on big-endian systems in a long time, if ever, and I have no way to test it. It's well possible that this driver has not been used by anyone in a while, the last patch that looks like it was tested on the hardware is from 2008.

2012-11-15TTY: call tty_port_destroy in the rest of driversJiri Slaby
After commit "TTY: move tty buffers to tty_port", the tty buffers are not freed in some drivers. This is because tty_port_destructor is not called whenever a tty_port is freed. This was an assumption I counted with but was unfortunately untrue. So fix the drivers to fulfil this assumption. To be sure, the TTY buffers (and later some stuff) are gone along with the tty_port, we have to call tty_port_destroy at tear-down places. This is mostly where the structure containing a tty_port is freed. This patch does exactly that -- put tty_port_destroy at those places.

2012-08-13TTY: use tty_port_register_deviceJiri Slaby
Currently we have no way to assign tty->port while performing tty installation. There are two ways to provide the link tty_struct => tty_port. Either by calling tty_port_install from tty->ops->install or tty_port_register_device called instead of tty_register_device when the device is being set up after connected. In this patch we modify most of the drivers to do the latter. When the drivers use tty_register_device and we have tty_port already, we switch to tty_port_register_device. So we have the tty_struct => tty_port link for free for those.

2011-04-25Char: nozomi, remove port.count checksJiri Slaby
Before 33dd474a, these were some kind of protection against race with HUP. They were protected with port->tty_sem at the same time. By that commit, the counting was switched to tty_port's one, but the locking remained the old one. So the count was not protected by any lock anymore. The driver should not test whether it raced with HUP or not anyways. With the new refcounted tty model, it just should proceed as nothing happened because all needed info is still there. In respect to this, let's drop the useless and unprotected tests (tty_port->count is protected by tty_port->lock).
