video: console: add missing MODULE_DESCRIPTION() macros

2024-06-22T07:52:36Z

With ARCH=i386, make allmodconfig && make W=1 C=1 reports: WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/video/console/mdacon.o Add the missing invocation of the MODULE_DESCRIPTION() macro to all files which have a MODULE_LICENSE(). This includes three other files which, although they did not produce a warning with the i386 allmodconfig configuration, may cause this warning with other configurations.

tty: vt: make consw::con_font_default()'s name const

2024-01-28T02:08:54Z

It's a name after all and that is not supposed to be changed. So make it const to make this obvious. Signed-off-by: "Jiri Slaby (SUSE)" Cc: "James E.J.

tty: vt: make font of consw::con_font_set() const

2024-01-28T02:08:54Z

Provided the font parameter of consw::con_font_set() is not supposed to be changed, make it const. Signed-off-by: "Jiri Slaby (SUSE)" Cc: Helge Deller Cc: "James E.J.

tty: vt: make types around consw::con_blank() bool

2024-01-28T02:08:54Z

Both the mode_switch parameter and the return value (a redraw needed) are true/false. So switch them to bool, so that users won't return -Eerrors or anything else. And document the hook.

tty: vt: use enum constants for VESA blanking modes

2024-01-28T02:08:54Z

Use the new enum for VESA constants. This improves type checking in consw::con_blank(). Signed-off-by: "Jiri Slaby (SUSE)" Cc: Helge Deller Cc: "James E.J.

tty: vt: use VESA blanking constants

2024-01-28T02:08:54Z

There are VESA blanking constants defined in vesa.h. So use them in the console code instead of constant values. Signed-off-by: "Jiri Slaby (SUSE)" Cc: Helge Deller Cc: "James E.J.

tty: vt: make consw::con_switch() return a bool

2024-01-28T02:08:54Z

The non-zero (true) return value from consw::con_switch() means a redraw is needed. So make this return type a bool explicitly instead of int. The latter might imply that -Eerrors are expected. They are not. And document the hook. Signed-off-by: "Jiri Slaby (SUSE)" Cc: Helge Deller Cc: "James E.J.

tty: vt: remove CM_* constants

2024-01-28T02:08:54Z

There is no difference between CM_MOVE and CM_DRAW. Either of them enables the cursor. CM_ERASE then disables cursor. So get rid of all of them and use simple "bool enable". Note that this propagates down to the fbcon code. And document the hook. Signed-off-by: "Jiri Slaby (SUSE)" Cc: Helge Deller Cc: "James E.J.

consoles: use if instead of switch-case in consw::con_cursor()

2024-01-28T02:08:54Z

This is only a preparation for the following cleanup patch to make it easier. Provided CM_ERASE is the only different, use 'if' instead of 'switch+case' in all those.

tty: vt: sanitize consw::con_putcs() parameters

2024-01-28T02:08:54Z

Similar to con_putc() in the previous patch: * make the pointer to charattr a pointer to u16, and * make x, y, and count unsigned as they are strictly non-negative. And again, document that hook.
