fbdev: svgalib: Clean up coding style

2025-07-27T17:56:51+00:00

This patch addresses various coding style issues in `svgalib.c` to improve readability and better align the code with the Linux kernel's formatting standards. The changes primarily consist of: - Adjusting whitespace around operators and after keywords. - Standardizing brace placement for control flow statements. - Removing unnecessary braces on single-statement if/else blocks. - Deleting extraneous blank lines throughout the file. These changes are purely stylistic and introduce no functional modifications. Signed-off-by: Darshan R. Signed-off-by: Helge Deller

fbcon: Increase maximum font width x height to 64 x 128

2024-03-16T07:29:48+00:00

By using bitmaps we actually support whatever size we would want, but the console currently limits fonts to 64x128 (which gives 60x16 text on 4k screens), so we don't need more for now, and we can easily increase later. Signed-off-by: Samuel Thibault Signed-off-by: Helge Deller

drm/i915: Move abs_diff() to math.h

abs_diff() belongs to math.h. Move it there. This will allow others to use it.

fbdev: move fbdev core files to separate directory

2014-04-17T05:10:19+00:00

Instead of having fbdev framework core files at the root fbdev directory, mixed with random fbdev device drivers, move the fbdev core files to a separate core directory. This makes it much clearer which of the files are actually part of the fbdev framework, and which are part of device drivers.
