* braille_console: remove MODULE_LICENSE in non-modulesNick Alcock2023-04-131-1/+0
| | | | | | | | | | | | | | | | | | | | Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

* tty/vt: consolemap: make parameters of inverse_translate() sanerJiri Slaby2022-06-101-1/+1
| | | | | | | | | | | | | - int use_unicode -> bool: it's used as bool at some places already, so make it explicit. - int glyph -> u16: every caller passes a u16 in. So make it explicit too. And remove a negative check from inverse_translate() as it never could be negative.

* vc: separate stateJiri Slaby2020-06-241-5/+5
| | | | | | | | | | | | | | | | | | | | | There are two copies of some members of struct vc_data. This is because we need to save them and restore later. Move these memebers to a separate structure called vc_state. So now instead of members like: vc_x, vc_y and vc_saved_x, vc_saved_y we have state and saved_state (of type: struct vc_state) containing state.x, state.y and saved_state.x, saved_state.y This change: * makes clear what is saved & restored * eases save & restore by using memcpy (see save_cur and restore_cur) Finally, we document the newly added struct vc_state using kernel-doc.

* vt:tackle kbd_tableAlan Cox2012-03-081-6/+3
| | | | | | | | | | | | | | | | | | | | | Keyboard struct lifetime is easy, but the locking is not and is completely ignored by the existing code. Tackle this one head on - Make the kbd_table private so we can run down all direct users - Hoick the relevant ioctl handlers into the keyboard layer - Lock them with the keyboard lock so they don't change mid keypress - Add helpers for things like console stop/start so we isolate the poking around properly - Tweak the braille console so it still builds There are a couple of FIXME locking cases left for ioctls that are so hideous they should be addressed in a later patch. After this patch the kbd_table is private and all the keyboard jiggery pokery is in one place. This update fixes speakup and also a memory leak in the original.
