fbdev/core: Clean up include statements in fbmem.c

2023-09-11T13:12:38+00:00

Remove all unnecessary include statements from fbmem.c. Most of
them were for functionality that has meanwhile been moved into
other files.

fbdev/core: Move logo functions into separate source file

2023-09-11T13:12:35+00:00

Move the fbdev function for displaying boot-up logos into their
own file fb_logo.c. Only build fb_logo.c if CONFIG_LOGO has been
selected. No functional changes.

v2:
	* include fb_internal.h (kernel test robot)
	* simplify option-parsing ifdefs
	* build fb_logo.o iff CONFIG_LOGO has been set

fbdev/core: Unexport logo helpers

2023-09-11T13:12:33+00:00

The interfaces for the fbdev logo are not used outside of the fbdev
module. Hence declare the fbdev logo functions in the internal header
file and remove their symbol exports. Only build the functions if
CONFIG_LOGO has been selected.

fbdev/core: Fix style of code for boot-up logo

2023-09-11T13:12:32+00:00

Fix a number of warnings from checkpatch.pl in this code before
moving it into a separate file. This includes

 * Prefer 'unsigned int' to bare use of 'unsigned'
 * space required after that ',' (ctx:VxV)
 * space prohibited after that open parenthesis '('
 * suspect code indent for conditional statements (16, 32)
 * braces {} are not necessary for single statement blocks

No functional changes.

fbdev/core: Rework fb init code

2023-06-27T07:58:51+00:00

Init the class "graphics" before the rest of fbdev. Later steps, such
as the sysfs code, depend on the class. Also arrange the module's exit
code in reverse order.

Unexport the global variable fb_class, which is only shared internally
within the fbdev core module.

fbdev/core: Move file-I/O code into separate file

2023-06-27T07:58:51+00:00

Move fbdev's file-I/O code into a separate file and contain it in
init and cleanup helpers. No functional changes.

	* add missing file fb_chrdev.c

fbdev/core: Move procfs code to separate file

2023-06-27T07:58:51+00:00

Move fbdev's procfs code into a separate file and contain it in
init and cleanup helpers. For the cleanup, replace remove_proc_entry()
with proc_remove(). It is equivalent in functionality, but looks
more like an inverse of proc_create_seq().

v2:
	* document proc_remove() usage (Sam)
	* revert unrelated removal of for_each_registered_fb()

fbdev/core: Add fb_device_{create,destroy}()

2023-06-27T07:58:51+00:00

Move the logic to create and destroy fbdev devices into the new
helpers fb_device_create() and fb_device_destroy().

There was a call to fb_cleanup_device() in do_unregister_framebuffer()
that was too late. The device had already been removed at this point.
Move the call into fb_device_destroy().

Declare the helpers in the new internal header file  fb_internal.h, as
they are only used within the fbdev core module.

fbdev/core: Pass Linux device to pm_vt_switch_*() functions

2023-06-27T07:58:50+00:00

Pass the Linux device to pm_vt_switch_*() instead of the virtual
fbdev device. Prepares fbdev for making struct fb_info.dev optional.

The type of device that is passed to the PM functions does not matter
much. It is only a token within the internal list of known devices.
The PM functions do not refer to any of the device's properties or its
type.
