.RE
.PP
\fIfb_helper\fR
.RS 4
driver\-allocated fbdev helper structure to initialize
.RE

.RS 4
maximum number of crtcs to support in this fbdev emulation

.SH "DESCRIPTION"
.PP
This allocates the structures for the fbdev helper with the given limits\&. Note that this won\*(Aqt yet touch the hardware (through the driver interfaces) nor register the fbdev\&. This is only done in
\fBdrm_fb_helper_initial_config\fR
to allow driver writes more control over the exact init sequence\&.
.PP
Drivers must set fb_helper\->funcs before calling
\fBdrm_fb_helper_initial_config\fR\&.
.SH "RETURNS"
.PP
Zero if everything went ok, nonzero otherwise\&.
