NAME
fb_find_mode - finds a valid video mode
SYNOPSIS
int __init fb_find_mode (struct fb_var_screeninfo *var, struct fb_info
*info, const char *mode_option, const struct fb_videomode *db, unsigned
int dbsize, const struct fb_videomode *default_mode, unsigned int
default_bpp);
ARGUMENTS
var frame buffer user defined part of display
info frame buffer info structure
mode_option string video mode to find
db video mode database
dbsize size of db
default_mode
default video mode to fall back to
default_bpp default color depth in bits per pixel
DESCRIPTION
Finds a suitable video mode, starting with the specified mode in
mode_option with fallback to default_mode. If default_mode fails, all
modes in the video mode database will be tried.
Valid mode specifiers for mode_option:
<xres>x<yres>[-<bpp>][@<refresh>] or
<name>[-<bpp>][@<refresh>]
with <xres>, <yres>, <bpp> and <refresh>
decimal numbers and <name> a string.
NOTE
The passed struct var is _not_ cleared! This allows you to supply
values for e.g. the grayscale and accel_flags fields.
Returns zero for failure, 1 if using specified mode_option, 2 if using
specified mode_option with an ignored refresh rate, 3 if default mode
is used, 4 if fall back to any valid mode.
