37df9f3fed video: hyperv_fb: Fix a double free in hvfb_probe
Function hvfb_probe() calls hvfb_getmem(), expecting upon return that
info->apertures is either NULL or points to memory that should be freed
by framebuffer_release().  But hvfb_getmem() is freeing the memory and
leaving the pointer non-NULL, resulting in a double free if an error
occurs or later if hvfb_remove() is called.

Fix this by removing all kfree(info->apertures) calls in hvfb_getmem().
This will allow framebuffer_release() to free the memory, which follows
the pattern of other fbdev drivers.

39a3898abf fbdev: atyfb: always declare aty_{ld,st}_lcd()
The previously added stubs for aty_{ld,}st_lcd() make it
so that these functions are used regardless of the config
options that were guarding them, so remove the #ifdef/#endif
lines and make their declarations always visible.
This fixes build warnings that were reported by clang:

   drivers/video/fbdev/aty/atyfb_base.c:180:6: warning: no previous prototype for function 'aty_st_lcd' [-Wmissing-prototypes]
   void aty_st_lcd(int index, u32 val, const struct atyfb_par *par)

3fd269e74f amba: Make the remove callback return void
All amba drivers return 0 in their remove callback. Together with the
driver core ignoring the return value anyhow, it doesn't make sense to
return a value here.

Change the remove prototype to return void, which makes it explicit that
returning an error value doesn't work as expected. This simplifies changing
the core remove callback to return void, too.

bb6dafdba6 video: omapfb2: Make standard and custom DSI command mode panel driver mutually exclusive
Standard DRM panel driver for DSI command mode panel used by omapfb2 is also
available now. Just like the other panels its module name clashes with the
module from drivers/video/fbdev/omap2/omapfb/displays, part of the deprecated
omapfb2 fbdev driver. As omapfb2 can only be compiled when the omapdrm driver
is disabled, and the DRM panel drivers are useless in that case, make the
omapfb2 panel depend on the standard DRM panels being disabled to fix
the name clash.

Coverity reported:

    Useless call (USELESS_CALL) side_effect_free: Calling
     SiS_GetResInfo(SiS_Pr, ModeNo, ModeIdIndex) is only useful for its

And this is correct - so drop the call.

4aca4dbcac video: fbdev: controlfb: Fix set but not used warnings
The controlfb driver has a number of dummy defines for IO operations.
They were introduced in commit a07a63b0e2
("video: fbdev: controlfb: add COMPILE_TEST support").

The write variants did not use their value parameter in the
dummy versions, resulting in set but not used warnings.
Fix this by adding "(void)val" to silence the compiler.

6d247e4d26 powerpc/ps3: make system bus's remove and shutdown callbacks return void
The driver core ignores the return value of struct device_driver::remove
because there is only little that can be done. For the shutdown callback
it's ps3_system_bus_shutdown() which ignores the return value.

To simplify the quest to make struct device_driver::remove return void,
let struct ps3_system_bus_driver::remove return void, too. All users
already unconditionally return 0, this commit makes it obvious that
returning an error code is a bad idea and ensures future users behave
accordingly.

57e4bc8a48 video: fbdev: sstfb: Updated logging to fix set but not used warnings
Fix set but not used warnings by introducing no_printk variants
for the internal logging system for this driver.

Fix a new warning that popped up now that logging was checked for
correct printf format strings.

A more invasive fix had been to replace all the internal logging with
standard logging primitives - thats for another day.

2a74e8682a video: fbdev: sis: Fix set but not used warnings in init.c
Fix "set but not used" warnings by removing the code the assign the
variables and the definition of the variables.
A register read is kept as it may have unknown side-effects.

This removes a lot of unused code - which is always a good thing to do.

50b82a2d69 video: fbdev: sis: Fix defined but not used warnings
init.h defines static symbols, so it should only be included
once. Drop the include from sis.h as it is not needed.
This fixes a lot of warnings seen with a W=1 build.
