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.

tty: srmcons: fix retval from srmcons_init()

2025-03-20T15:00:51+00:00

The value returned from srmcons_init() was -ENODEV for over 2 decades.
But it does not matter, given device_initcall() ignores retvals.

But to be honest, return 0 in case the tty driver was registered
properly.

To do that, the condition is inverted and a short path taken in case of
error.

err_free_drv is introduced as it will be used from more places later.

tty: srmcons: convert to u8 and size_t

2023-12-08T11:02:38+00:00

Switch character types to u8 and sizes to size_t. To conform to
characters/sizes in the rest of the tty layer.

tty: srmcons: remove 'str_cr' and use string directly

2023-11-28T19:17:06+00:00

'str_cr' contains a single character: \r. There is no need to declare it
as array. Instead, pass the character (as a string) to callback_puts()
directly. This ensures the string is in proper .rodata (const) section
and makes the code more obvious.

tty: srmcons: switch need_cr to bool

2023-11-28T19:17:06+00:00

'need_cr' is a flag, so type it properly to be a 'bool'. Move the
declaration into the loop too. That ensures the variable is initialized
properly even if the code was moved somehow.

tty: srmcons: use 'count' directly in srmcons_do_write()

2023-11-28T19:17:06+00:00

Similarly to 'buf' in the previous patch, there is no need to have a
separate counter ('remaining') in srmcons_do_write(). 'count' can be
used directly which simplifies the code a bit.

Note that the type of the current count ('c') is changed from 'long' to
'size_t' so that:
1) it is prepared for the upcoming change of 'count's type, and
2) is unsigned.

tty: srmcons: make srmcons_do_write() return void

2023-11-28T19:17:06+00:00

The return value of srmcons_do_write() is ignored as all characters are
pushed. So make srmcons_do_write() to return void.

tty: srmcons: use 'buf' directly in srmcons_do_write()

2023-11-25T07:23:18+00:00

There is no need to have a separate iterator ('cur') through 'buf' in
srmcons_do_write(). 'buf' can be used directly which simplifies the code
a bit.
