suppress_bind_attrs
On today's platforms the memory savings of putting the remove function
in .exit isn't that relevant any more. It only matters for built-in
drivers and typically saves a few 100k.
The downside is that the driver cannot be unbound at runtime which is
ancient and also slightly complicates testing. Also it requires to mark
the driver struct with __refdata which is needed to suppress a (W=1)
modpost warning:
WARNING: modpost: drivers/video/fbdev/omap2/omapfb/displays/panel-dpi: section mismatch in reference: panel_dpi_driver+0x4 (section: .data) -> panel_dpi_remove (section: .exit.text)
To simplify matters, move the remove callback to .text and drop
.suppress_bind_attrs = true.

On today's platforms the benefit of platform_driver_probe() isn't that
relevant any more. It allows to drop some code after booting (or module
loading) for .probe() and discard the .remove() function completely if
the driver is built-in. This typically saves a few 100k.
The downside of platform_driver_probe() is that the driver cannot be
bound and unbound at runtime which is ancient and also slightly
complicates testing. There are also thoughts to deprecate
platform_driver_probe() because it adds some complexity in the driver
core for little gain. Also many drivers don't use it correctly. This
driver for example misses to mark the driver struct with __refdata which
is needed to suppress a (W=1) modpost warning:

I've re-written the error handling but the bug is that if init_imstt()
fails we need to call iounmap(par->cmap_regs).

The init_imstt() function calls framebuffer_release() on error and then
the probe() function calls it again. It should only be done in probe.

viafbdev.c utilizes memdup_user() to copy an array from userspace.
There is a new wrapper, specifically designed for copying arrays. Use
this one instead.

OMAP2_VRFB is a bool, so the vrfb driver can never be compiled as a
module. With that __exit_p(vrfb_remove) always evaluates to NULL and
vrfb_remove() is unused.
If the driver was compilable as a module, it would fail to build because
the type of vrfb_remove() isn't compatible with struct
platform_driver::remove(). (The former returns void, the latter int.)

The kfd_resume needs to touch GC registers to enable the interrupts,
it needs to be done before GFXOFF is enabled to ensure that the GFX is
not off and GC registers can be touched. So move kfd_resume before the
amdgpu_device_ip_late_init which enables the CGPG/GFXOFF.

Doorbell rptr/wptr can be set through multiple ways including direct
register initialization. Disable doorbell during hw_fini once the ring
is disabled so that during next module reload direct initialization
takes effect. Also, move the direct initialization after minor update is
set to 1 since rptr/wptr are reinitialized back to 0 which could be
lower than the previous doorbell value (ex: cases like module reload).

Populate stream's test pattern type and color space fields before
calling into DC to program DP test pattern.
