I agree that it's a no-op, but code is not just about functionality but also readability, isn't it? Also, I prefer "sh:" as the architecture prefix, not "arch/sh:". Thanks, Adrian

I won't argue with that, but the flag itself is wrong. FBINFO_FLAG_DEFAULT is/was for struct fb_info.flags. You have struct fb_videomode.flag. The valid flags for this field are at [1]. If anything, the field could be initialized to FB_MODE_IS_UNKNOWN, which has the same value.

FBINFO_FLAG_DEFAULT is a flag for a framebuffer in struct fb_info. Flags for videomodes are prefixed with FB_MODE_. FBINFO_FLAG_DEFAULT is 0 and the static declaration already clears the memory area of sh7763fb_videomode. So remove the assignment.
