request_region should be used with release_region, not request_mem_region.
Geert Uytterhoeven pointed out that in the case of drivers/video/gbefb.c,
the problem is actually the other way around; request_mem_region should be
used instead of request_region.

Following issues have been addressed on DA8XX/OMAP-L1XX:
a. Screen misalignment during booting when frame buffer console is
enabled.
b. Driver was configured always in PSEUDOCOLOR mode. This patch
dynamically configures the driver either in PSEUDOCOLOUR or TRUECOLOR
mode depending on bpp.
c. The RED and BLUE offsets were interchanged resulting in wrong
bootup logo colour.
This patch has been tested on DA830/OMAP-L137 and DA850/OMAP-L138 EVMs.

pxafb_pan_display() used to ignore the fb_var_screeninfo parameter. Now
pass it to setup_base_frame() instead of pulling default values out of
fb_info.
And the original patch has an issue of pxafb_pan_display() paying only
attention to the 'var' parameter passed in, and Ville Syrjälä pointed
out, this is potentially dangerous as user could pass in any other
screeninfo parameters as well, and not only such that are relevant for
display panning. This is fixed by limiting the arguments actually used
to .xoffset, .yoffset and .vmode & FB_VMODE_YWRAP.

Remove fb_save_state() and fb_restore_state operations from frame buffer layer.
They are used only in two drivers:
1. savagefb - and cause bug #11248
2. uvesafb
Usage of these operations is misunderstood in both drivers so kill these
operations, fix the bug #11248 and avoid confusion in the future.
Tested on Savage 3D/MV card and the patch fixes the bug #11248.
The frame buffer layer uses these funtions during switch between graphics
and text mode of the console, but these drivers saves state before
switching of the frame buffer (in the fb_open) and after releasing it (in
the fb_release). This defeats the purpose of these operations.

fbdev: add mutex for fb_mmap locking
In which a mutex was added when changing smem_start and smem_len fields,
so the mutex inside the fb_mmap() call is actually used.
The problem was that set_fb_fix, which modifies the above 2 fields,
was called before and after registering the framebuffer,
which when used before registration, lead to a failed attempt to
use an uninitialized mutex.
Solution: Don't use mutex before framebuffer registration.

fbcon makes the (reasonable) assumption that it only needs to program the
hardware once, when fbcon_init() is called for the foreground console.
This doesn't always play well with vgacon because vgacon_deinit() is only
doing its job when the last console it owns is closed (when switching from
vgacon to fbcon, that's usually *after* fbcon_init() has set the new
mode).
Depending on the hardware this can cause the wrong framebuffer location to
be scanned out (e.g. reproduced on nv05 with the nouveau framebuffer
driver).

Attempting to unload a framebuffer module calls unregister_framebuffer()
which in turn gets fbcon to release it. If fbcon has no framebuffers
linked to a console, it will also unbind itself from the console driver.
However, if fbcon never registered itself as a console driver, the unbind
will fail causing the framebuffer device entry to persist. In most cases
this failure will result in an oops when attempting to access the now
non-existent device.
This patch ensures that the fbcon unbind request will succeed even if a
bind was never done. It tracks if a successful bind ever occurred & will
only attempt to unbind if needed. If there never was a bind, it simply
returns with no error.
