The fb_var_screeninfo case is analogous. // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct fb_fix_screeninfo i@p = { ... }; @ok@ identifier r.i; expression e; position p; @@ e = i@p @bad@ position p != {r.p,ok.p}; identifier r.i; struct fb_fix_screeninfo e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct fb_fix_screeninfo i = { ... }; // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- drivers/video/fbdev/arcfb.c | 4 ++-- drivers/video/fbdev/asiliantfb.c | 4 ++-- drivers/video/fbdev/aty/aty128fb.c | 6 +++--- drivers/video/fbdev/aty/atyfb_base.c | 2 +- drivers/video/fbdev/aty/radeon_monitor.c | 2 +- drivers/video/fbdev/hecubafb.c | 4 ++-- drivers/video/fbdev/hgafb.c | 2 +- drivers/video/fbdev/i740fb.c | 2 +- drivers/video/fbdev/kyro/fbdev.c | 2 +- drivers/video/fbdev/pm2fb.c | 2 +- drivers/video/fbdev/s1d13xxxfb.c | 2 +- drivers/video/fbdev/savage/savagefb_driver.c | 2 +- drivers/video/fbdev/simplefb.c | 4 ++-- drivers/video/fbdev/sm712fb.c | 2 +- drivers/video/fbdev/ssd1307fb.c | 4 ++-- drivers/video/fbdev/tdfxfb.c | 4 ++-- drivers/video/fbdev/uvesafb.c | 2 +- drivers/video/fbdev/vfb.c | 2 +- drivers/video/fbdev/vga16fb.c | 2 +- 19 files changed, 27 insertions(+), 27 deletions(-) diff --git a/drivers/video/fbdev/simplefb.c b/drivers/video/fbdev/simplefb.c index e9cf199..85775df 100644 --- a/drivers/video/fbdev/simplefb.c +++ b/drivers/video/fbdev/simplefb.c @@ -33,14 +33,14 @@ #include <linux/parser.h> #include <linux/regulator/consumer.h> -static struct fb_fix_screeninfo simplefb_fix = { +static const struct fb_fix_screeninfo simplefb_fix = { .id = "simple", .type = FB_TYPE_PACKED_PIXELS, .visual = FB_VISUAL_TRUECOLOR, .accel = FB_ACCEL_NONE, }; -static struct fb_var_screeninfo simplefb_var = { +static const struct fb_var_screeninfo simplefb_var = { .height = -1, .width = -1, .activate = FB_ACTIVATE_NOW, diff --git a/drivers/video/fbdev/asiliantfb.c b/drivers/video/fbdev/asiliantfb.c index 7e8ddf0..91eea45 100644 --- a/drivers/video/fbdev/asiliantfb.c +++ b/drivers/video/fbdev/asiliantfb.c @@ -474,7 +474,7 @@ static void chips_hw_init(struct fb_info *p) write_fr(chips_init_fr[i].addr, chips_init_fr[i].data); } -static struct fb_fix_screeninfo asiliantfb_fix = { +static const struct fb_fix_screeninfo asiliantfb_fix = { .id = "Asiliant 69000", .type = FB_TYPE_PACKED_PIXELS, .visual = FB_VISUAL_PSEUDOCOLOR, @@ -483,7 +483,7 @@ static struct fb_fix_screeninfo asiliantfb_fix = { .smem_len = 0x200000, /* 2MB */ }; -static struct fb_var_screeninfo asiliantfb_var = { +static const struct fb_var_screeninfo asiliantfb_var = { .xres = 640, .yres = 480, .xres_virtual = 640, diff --git a/drivers/video/fbdev/aty/atyfb_base.c b/drivers/video/fbdev/aty/atyfb_base.c index f34ed47f..11026e7 100644 --- a/drivers/video/fbdev/aty/atyfb_base.c +++ b/drivers/video/fbdev/aty/atyfb_base.c @@ -212,7 +212,7 @@ struct pci_mmap_map { unsigned long prot_mask; }; -static struct fb_fix_screeninfo atyfb_fix = { +static const struct fb_fix_screeninfo atyfb_fix = { .id = "ATY Mach64", .type = FB_TYPE_PACKED_PIXELS, .visual = FB_VISUAL_PSEUDOCOLOR, diff --git a/drivers/video/fbdev/hecubafb.c b/drivers/video/fbdev/hecubafb.c index e4031ef..8577195 100644 --- a/drivers/video/fbdev/hecubafb.c +++ b/drivers/video/fbdev/hecubafb.c @@ -47,7 +47,7 @@ #define DPY_W 600 #define DPY_H 800 -static struct fb_fix_screeninfo hecubafb_fix = { +static const struct fb_fix_screeninfo hecubafb_fix = { .id = "hecubafb", .type = FB_TYPE_PACKED_PIXELS, .visual = FB_VISUAL_MONO01, @@ -58,7 +58,7 @@ static struct fb_fix_screeninfo hecubafb_fix = { .accel = FB_ACCEL_NONE, }; -static struct fb_var_screeninfo hecubafb_var = { +static const struct fb_var_screeninfo hecubafb_var = { .xres = DPY_W, .yres = DPY_H, .xres_virtual = DPY_W, diff --git a/drivers/video/fbdev/i740fb.c b/drivers/video/fbdev/i740fb.c index cf5ccd0..7bc5f60 100644 --- a/drivers/video/fbdev/i740fb.c +++ b/drivers/video/fbdev/i740fb.c @@ -82,7 +82,7 @@ struct i740fb_par { #define DACSPEED24_SD 128 #define DACSPEED32 86 -static struct fb_fix_screeninfo i740fb_fix = { +static const struct fb_fix_screeninfo i740fb_fix = { .id = "i740fb", .type = FB_TYPE_PACKED_PIXELS, .visual = FB_VISUAL_TRUECOLOR, diff --git a/drivers/video/fbdev/kyro/fbdev.c b/drivers/video/fbdev/kyro/fbdev.c index 5bb0153..f77478f 100644 --- a/drivers/video/fbdev/kyro/fbdev.c +++ b/drivers/video/fbdev/kyro/fbdev.c @@ -44,7 +44,7 @@ static struct fb_fix_screeninfo kyro_fix = { .accel = FB_ACCEL_NONE, }; -static struct fb_var_screeninfo kyro_var = { +static const struct fb_var_screeninfo kyro_var = { /* 640x480, 16bpp @ 60 Hz */ .xres = 640, .yres = 480, diff --git a/drivers/video/fbdev/pm2fb.c b/drivers/video/fbdev/pm2fb.c index aa8d288..1a4070f 100644 --- a/drivers/video/fbdev/pm2fb.c +++ b/drivers/video/fbdev/pm2fb.c @@ -113,7 +113,7 @@ static struct fb_fix_screeninfo pm2fb_fix = { /* * Default video mode.
