So do not set it. Flags should signal differences from the default values. After cleaning up all occurrences of FBINFO_DEFAULT, the token will be removed. v4: * clarify commit message (Geert, Dan) v2: * fix commit message (Miguel) Signed-off-by: Thomas Zimmermann Acked-by: Sam Ravnborg Cc: Jaya Kumar Cc: Helge Deller Cc: Peter Jones Cc: Sascha Hauer Cc: Pengutronix Kernel Team Cc: Shawn Guo Cc: Fabio Estevam Cc: NXP Linux Team Cc: Maik Broemme Cc: Jingoo Han Cc: Sudip Mukherjee Cc: Teddy Wang Cc: Michal Januszewski --- drivers/video/fbdev/arcfb.c | 1 - drivers/video/fbdev/aty/aty128fb.c | 1 - drivers/video/fbdev/broadsheetfb.c | 2 +- drivers/video/fbdev/da8xx-fb.c | 1 - drivers/video/fbdev/efifb.c | 1 - drivers/video/fbdev/goldfishfb.c | 1 - drivers/video/fbdev/gxt4500.c | 3 +-- drivers/video/fbdev/hecubafb.c | 2 +- drivers/video/fbdev/imxfb.c | 3 +-- drivers/video/fbdev/intelfb/intelfbdrv.c | 1 - drivers/video/fbdev/metronomefb.c | 2 +- drivers/video/fbdev/mx3fb.c | 1 - drivers/video/fbdev/omap/omapfb_main.c | 1 - drivers/video/fbdev/omap2/omapfb/omapfb-main.c | 1 - drivers/video/fbdev/s3c-fb.c | 1 - drivers/video/fbdev/sh_mobile_lcdcfb.c | 2 -- drivers/video/fbdev/sis/sis_main.c | 2 -- drivers/video/fbdev/sm501fb.c | 2 +- drivers/video/fbdev/sm712fb.c | 1 - drivers/video/fbdev/uvesafb.c | 3 +-- drivers/video/fbdev/vesafb.c | 2 +- drivers/video/fbdev/vfb.c | 1 - drivers/video/fbdev/vga16fb.c | 2 +- drivers/video/fbdev/xen-fbfront.c | 2 +- 24 files changed, 10 insertions(+), 29 deletions(-) diff --git a/drivers/video/fbdev/arcfb.c b/drivers/video/fbdev/arcfb.c index 9aaea3be8281..cff11cb04a55 100644 --- a/drivers/video/fbdev/arcfb.c +++ b/drivers/video/fbdev/arcfb.c @@ -546,7 +546,6 @@ static int arcfb_probe(struct platform_device *dev) par->c2io_addr = c2io_addr;
