stdio: fix stdio_deregister_dev()

2023-10-09T19:24:31+00:00

When copying the name of a stdio device we must ensure that it is NUL
terminated before passing it to strcmp() to avoid a buffer overrun.

Truncating the name field leads to failure to deregister a stdio device.
When copying we must ensure that the name field sizes match.

Addresses-Coverity-ID: 350462 String not null terminated

stdio: Fix class iteration in stdio_add_devices()

2022-10-18T03:17:12+00:00

There is a complaint in the code that iterates keyboards that we don't
have the _check variant of class iterator but we in fact do, use it.

In the code that iterates video devices there is an attempt to print
errors but the simple iterator does not return a device when there is an
error. Use the _check variant of the iterator as well.

Also format error messages consistently.

serial: Implement serial_flush() function for console flush() fallback

2022-09-24T15:34:37+00:00

Like in all other console functions, implement also serial_flush() function
as a fallback int console flush() function.

Flush support is available only when config option CONSOLE_FLUSH_SUPPORT is
enabled. So when it is disabled then provides just empty static inline
function serial_flush().

video: Drop references to CONFIG_VIDEO et al

2022-03-28T18:17:07+00:00

Drop the Kconfigs which are not used and all references to them. In
particular, this drops CONFIG_VIDEO to avoid confusion and allow us to
eventually rename CONFIG_DM_VIDEO to CONFIG_VIDEO.

Also drop the prototype for video_get_info_str() which is no-longer used.
