treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

tty: vcc: Add check for kstrdup() in vcc_probe()

2023-09-18T09:14:42+00:00

Add check for the return value of kstrdup() and return the error, if it fails in order to avoid NULL pointer dereference. Signed-off-by: Yi Yang Reviewed-by: Jiri Slaby Link: https://lore.kernel.org/r/20230904035220.48164-1-yiyang13@huawei.com Signed-off-by: Greg Kroah-Hartman

tty: vcc: convert counts to size_t

2023-08-11T19:12:47+00:00

Unify the type of tty_operations::write() counters with the 'count' parameter. I.e. use size_t for them. This includes changing vcc_port::chars_in_buffer to size_t to keep min() and avoid min_t().

tty: make tty_operations::write()'s count size_t

tty: drop put_tty_driver

2021-07-27T10:17:21+00:00

put_tty_driver() is an alias for tty_driver_kref_put(). There is no need for two exported identical functions, therefore switch all users of old put_tty_driver() to new tty_driver_kref_put() and remove the former for good.
