fbdev: Remove FBINFO_DEFAULT and FBINFO_FLAG_DEFAULT flags
|
expand

Remove the unused flags FBINFO_DEFAULT and FBINFO_FLAG_DEFAULT from fbdev and drivers, as briefly discussed at [1]. Both flags were maybe useful when fbdev had special handling for driver modules. With commit 376b3ff54c9a ("fbdev: Nuke FBINFO_MODULE"), they are both 0 and have no further effect. Patches 1 to 7 remove FBINFO_DEFAULT from drivers. Patches 2 to 5 split this by the way the fb_info struct is being allocated. All flags are cleared to zero during the allocation. Patches 8 to 16 do the same for FBINFO_FLAG_DEFAULT. Patch 8 fixes an actual bug in how arch/sh uses the token for struct fb_videomode, which is unrelated. Patch 17 removes both flag constants from <linux/fb.h> and patch 18 documents the zero'ed memory returned by framebuffer_alloc(). v4: * clarify commit messages (Geert, Dan) v3: * sh: include board name in commit message (Adrian) * docs: reword text (Miguel) v2: * sh: use FB_MODE_IS_UNKNOWN (Adrian) * fix commit messages (Miguel) * document framebuffer_alloc()'s zero'ed memory (Miguel) [1] https://lore.kernel.org/dri-devel/877crer8fm.fsf@minerva.mail-host-address-is-not-set/ Thomas Zimmermann (18): drm: Remove flag FBINFO_DEFAULT from fbdev emulation fbdev: Remove FBINFO_DEFAULT from static structs fbdev: Remove FBINFO_DEFAULT from kzalloc()'ed structs fbdev: Remove FBINFO_DEFAULT from devm_kzalloc()'ed structs fbdev: Remove FBINFO_DEFAULT from framebuffer_alloc()'ed structs fbdev/fsl-diu-fb: Remove flag FBINFO_DEFAULT vfio-mdev: Remove flag FBINFO_DEFAULT from fbdev sample driver sh: mach-sh7763rdp: Assign FB_MODE_IS_UNKNOWN to struct fb_videomode.flag auxdisplay: Remove flag FBINFO_FLAG_DEFAULT from fbdev drivers hid/picolcd: Remove flag FBINFO_FLAG_DEFAULT from fbdev driver media: Remove flag FBINFO_FLAG_DEFAULT from fbdev drivers staging: Remove flag FBINFO_FLAG_DEFAULT from fbdev drivers fbdev: Remove FBINFO_FLAG_DEFAULT from kzalloc()'ed structs fbdev: Remove FBINFO_FLAG_DEFAULT from framebuffer_alloc()'ed structs fbdev/atafb: Remove flag FBINFO_FLAG_DEFAULT fbdev/pxafb: Remove flag FBINFO_FLAG_DEFAULT fbdev: Remove FBINFO_DEFAULT and FBINFO_FLAG_DEFAULT fbdev: Document that framebuffer_alloc() returns zero'ed data arch/sh/boards/mach-sh7763rdp/setup.c | 2 +- drivers/auxdisplay/cfag12864bfb.c | 1 -
