Miguel Ojeda fe58103a56 cfag12864b fix
This one-liner patch fixes a bug in drivers/auxdisplay/cfag12864b.c

At cfag12864b_init(), the driver tries to kalloc some memory in the
variable cfag12864b_cache.

Then, as usual, it checks if the call failed. However, it checks
cfag12864b_buffer instead.

This patch changes the "cfag12864b_buffer" to "cfag12864b_cache" so the
correct variable is checked.

Jan Engelhardt f5920969fb Use menuconfig objects II - auxdisplay
Make a "menuconfig" out of the Kconfig objects "menu, ..., endmenu",
so that the user can disable all the options in that menu at once
instead of having to disable each option separately.

Avuton Olrich bfeeffbb4f cfag12864bfb: Use sys_ instead of cfb_ framebuffer accessors
Because the framebuffer memory is allocated system RAM, use the sys_ drawing
libraries. It also fixes the following compile error:

  LD      .tmp_vmlinux1
drivers/built-in.o:(.data+0x8b48): undefined reference to `cfb_fillrect'
drivers/built-in.o:(.data+0x8b50): undefined reference to `cfb_copyarea'
drivers/built-in.o:(.data+0x8b58): undefined reference to `cfb_imageblit'

[adaplas]
Use fb_sys_read/write for the same reasons as above.

Miguel Ojeda 34173a4aad [PATCH] cfag12864b: fix crash when built-in and no parport present
The problem comes when ks0108/cfag12864b are built-in and no parallel port is
present.  ks0108_init() is called first, as it should be, but fails to load
(as there is no parallel port to use).

After that, cfag12864b_init() gets called, without knowing anything about
ks0108 failed, and calls ks0108_writecontrol(), which dereferences an
uninitialized pointer.

Init order is OK, I think.  The problem is how to stop cfag12864b_init() being
called if ks0108 failed to load.  modprobe does it for us, but, how when
built-in?

  drivers.

- Add support for the ks0108 LCD Controller as a device driver.  (uses
  parport interface)

- Add support for the cfag12864b LCD as a device driver.  (uses ks0108
  LCD Controller driver)

- Add a framebuffer device called cfag12864bfb.  (uses cfag12864b LCD
