selection.c and vt.c still uses tabs in the kernel-doc. This misrenders the
functions in the output -- sphinx misinterprets the description. So
remove these tabs, incl. those around dashes.
'enum' keyword is needed before enum names. Fix that.
Superfluous \n after the comments are also removed. They are not
completely faulty, but this unifies all the kernel-doc in the files.
Finally fix up the cross references.

fbcon_screen_pos() performs the same as the default implementation. The
only difference in the default implementation is that is considers both
vc->vc_origin and vc->vc_visible_origin. But given fbcon's softscroll
code was already removed in commit 50145474f6ef (fbcon: remove soft
scrollback code), both are always the same.
So remove fbcon_screen_pos() too.

-1 is the same as VESA_VSYNC_SUSPEND in all con_blank() implementations.
So we can remove this special case from vgacon now too.
Despite con_blank() of fbcon looks complicated, the "if
(!fbcon_is_inactive(vc, info))" branch is not taken as we set
"ops->graphics = 1;" few lines above. So what matters there (as in all
other blank implementations except vgacon) is if 'blank' is zero or not.

All these consw::con_putc() implementations do the same as
consw::con_putcs() (only for one charattr) or even call
consw::con_putcs() on their own.
Drop them, as thanks to the new con_putc() helper in the previous patch,
the console code performs this already -- exactly if consw::con_putc()
is missing (NULL).

'count' in consw::con_clear() is guaranteed to be positive. csi_X() (the
only caller) takes the minimum of the vc parameter (which is at least 1)
and count of characters till the end of the line. The latter is computed
as a subtraction of vc->vc_cols (count) and vc->state.x (offset). So for
the worst case, full line, it is 1.
Therefore, there is no point in checking zero or negative values (width
is now unsigned anyway).

In consw::con_clear():
* Height is always 1, so drop it.
* Offsets and width are always unsigned values, so re-type them as such.
This needs a new __fbcon_clear() in the fbcon code to still handle
height which might not be 1 when called internally.
Note that tests for negative count/width are left in place -- they are
taken care of in the next patches.
And document the hook.

It is pretty unfortunate to set vc_data::vc_resize_user in two callers
of vc_do_resize(). vc_resize_user is immediately reset there (while
remembering it). So instead of this back and forth, pass 'from_user' as
a parameter.
Notes on 'int user':
* The name changes from 'user' to 'from_user' on some places to be
consistent.
* The type is bool now as 'int user' might evoke user's uid or whatever.
Provided vc_resize() is called on many places and they need not to care
about this parameter, its prototype is kept unchanged. Instead, it is
now an inline calling a new __vc_resize() which implements the above.
This patch makes the situation much more obvious.

Avoid costly user copies under the console lock. So push the lock down
from tioclinux() to sel_loadlut() and set_vesa_blanking().
It is now obvious what is actually protected.

Pass proper types and proper pointers (the data with an offset) to the
TIOCL_* handlers. So that they need not to cast or add anything to the
passed pointer.
This makes obvious what is passed/consumed.

At least since commits feebed6515a1 ("tty: shutdown method") and
bc1e99d93f09 ("TTY: vt, add ->install"), tty->driver_data in vc is
expected to be set since tty_operations::install() till ::cleanup().
So the checks of !tty->driver_data (aka !vc) in:
* vc_do_resize() by tty -> ioctl(TIOCSWINSZ) -> vt_resize()
* do_con_write() by tty -> tty_operations::write()/::put_char()
* con_flush_chars() by tty -> ::flush_chars()
are all superfluous. And also, holding a console lock is not needed to
fetch tty->driver_data.
Note there is even a stale comment in con_flush_chars() about a race
between that and con_close(). But con_close() does not set
tty->driver_data to NULL for years already.
Drop all these in a hope I am not terribly mistaken.

The if (c >= 20 && c <= 0x3f) test added in commit 7a99565f8732 is
wrong. 20 is DC4 in ascii and it makes no sense to consider that as the
bottom limit. Instead, it should be 0x20 as in the other test in
the commit above. This is supposed to NOT change anything as we handle
interesting 20-0x20 asciis far before this if.
So for sakeness, change to 0x20 (which is SPACE).

display_desc is a pointer to a RO string. Instead, switch display_desc
to a static array as we are used to. It BTW saves unnecessary 8B on the
stack.

This patch replaces max(a, min(b, c)) by clamp(b, a, c) in the solo6x10
driver. This improves the readability and more importantly, for the
solo6x10-p2m.c file, this reduces on my system (x86-64, gcc 13):
- the preprocessed size from 121 MiB to 4.5 MiB;
- the build CPU time from 46.8 s to 1.6 s;
- the build memory from 2786 MiB to 98MiB.
In fine, this allows this relatively simple C file to be built on a
32-bit system.
