USB: serial: omninet: add device id for Zyxel Omni 56K Plus

2021-06-16T09:36:35+00:00

commit fc0b3dc9a11771c3919eaaaf9d649138b095aa0f upstream. Add device id for Zyxel Omni 56K Plus modem, this modem include: USB chip: NetChip NET2888 Main chip: 901041A F721501APGF Another modem using the same chips is the Zyxel Omni 56K DUO/NEO, could be added with the right USB ID.

USB: serial: omninet: fix reference leaks at open

2017-03-18T11:14:32+00:00

commit 30572418b445d85fcfe6c8fe84c947d2606767d8 upstream. This driver needlessly took another reference to the tty on open, a reference which was then never released on close. This lead to not just a leak of the tty, but also a driver reference leak that prevented the driver from being unloaded after a port had once been opened.

USB: serial: omninet: fix NULL-derefs at open and disconnect

commit a5bc01949e3b19d8a23b5eabc6fc71bb50dc820e upstream. Fix NULL-pointer dereferences at open() and disconnect() should the device lack the expected bulk-out endpoints: Unable to handle kernel NULL pointer dereference at virtual address 000000b4 ...

usb: delete non-required instances of include

2014-01-08T23:01:39+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Signed-off-by: Paul Gortmaker Signed-off-by: Greg Kroah-Hartman

USB: omninet: switch to generic read implementation

USB: omninet: refactor read-urb processing

USB: omninet: clean up protocol defines

2013-04-17T17:05:34+00:00

Remove redundant data-offset define, which was really just the header length. Add payload-size define and use the bulk-out size define for the actual bulk-out size. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: omninet: use kzalloc for private data

TTY: switch tty_flip_buffer_push

2013-01-16T06:30:15+00:00

Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. Now, the one where most of tty_port_tty_get gets removed: tty_flip_buffer_push. IOW we also closed all the races in drivers not using tty_port_tty_get at all yet. Also we move tty_flip_buffer_push declaration from include/linux/tty.h to include/linux/tty_flip.h to all others while we are changing it anyway.
