fbdev: wm8505fb: select CONFIG_FB_IOMEM_FOPS

2024-10-21T09:16:51Z

The fb_io_mmap() function is used in the file operations but not enabled in all configurations unless FB_IOMEM_FOPS gets selected: ld.lld-20: error: undefined symbol: fb_io_mmap referenced by wm8505fb.c drivers/video/fbdev/wm8505fb.o:(wm8505fb_ops) in archive vmlinux.a Fixes: 11754a504608 ("fbdev/wm8505fb: Initialize fb_ops to fbdev I/O-memory helpers") Signed-off-by: Arnd Bergmann Reviewed-by: Thomas Zimmermann Signed-off-by: Helge Deller

fbdev: da8xx: remove the driver

2024-10-15T08:08:23Z

This driver is no longer used on any platform. It has been replaced by tilcdc on the two DaVinci boards we still support and can be removed. Signed-off-by: Bartosz Golaszewski Acked-by: Thomas Zimmermann Signed-off-by: Helge Deller

fbdev: Constify struct sbus_mmap_map

2024-10-15T08:07:32Z

'struct sbus_mmap_map' are not modified in these drivers. Constifying this structure moves some data to a read-only section, so increases overall security. Update sbusfb_mmap_helper() accordingly. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 2452 536 16 3004 bbc drivers/video/fbdev/bw2.o After: ===== text data bss dec hex filename 2500 483 16 2999 bb7 drivers/video/fbdev/bw2.o Signed-off-by: Christophe JAILLET Signed-off-by: Helge Deller

fbdev: sstfb: Make CONFIG_FB_DEVICE optional

2024-10-15T08:07:31Z

The sstfb driver currently depends on CONFIG_FB_DEVICE to create sysfs entries and access info->dev. This patch wraps the relevant code blocks with #ifdef CONFIG_FB_DEVICE, allowing the driver to be built and used even if CONFIG_FB_DEVICE is not selected. The sysfs setting only controls the VGA pass-through state and is not required for the display to work correctly. (See: http://vogonswiki.com/index.php/VGA_passthrough_cable for more information.) Added some fixes from Thomas Zimmermann. Signed-off-by: Gonzalo Silvalde Blanco Signed-off-by: Thomas Zimmermann Reviewed-by: Thomas Zimmermann Signed-off-by: Helge Deller

fbdev: Switch back to struct platform_driver::remove()

2024-10-08T19:47:18Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/video/fbdev to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files. Signed-off-by: Uwe Kleine-König Reviewed-by: Thomas Zimmermann Signed-off-by: Helge Deller

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

fbdev: sisfb: Fix strbuf array overflow

2024-09-27T22:42:11Z

The values of the variables xres and yres are placed in strbuf. These variables are obtained from strbuf1. The strbuf1 array contains digit characters and a space if the array contains non-digit characters. Then, when executing sprintf(strbuf, "%ux%ux8", xres, yres); more than 16 bytes will be written to strbuf. It is suggested to increase the size of the strbuf array to 24.

fbdev: omapfb: Call of_node_put(ep) only once in omapdss_of_find_source_for_first_ep()

2024-09-26T16:20:27Z

An of_node_put(ep) call was immediately used after a pointer check for a of_graph_get_remote_port() call in this function implementation. Thus call such a function only once instead directly before the check. This issue was transformed by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Helge Deller
