strcpy() performs no bounds checking on the destination buffer. This
could result in linear overflows beyond the end of the buffer, leading

Remove the initialization of the variable "i" since it is written a few
lines later.

Add braces to the "for" loop. This way, the kernel coding style is
followed.

Hi Tvrtko,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on drm-intel/for-linux-next]
[also build test ERROR on v5.14-rc3 next-20210730]
[If your patch is applied to the wrong git tree, kindly drop us a note.

This patchset adds support for emulating virtual hardware with VKMS.
The virtual hardware mode can be enabled by using the following command
while loading the module:
sudo modprobe vkms enable_virtual_hw=1
The first patch is prep work for adding virtual_hw mode and refactors
the plane comp
Add a new function vkms_composer_common(). The actual plane
composition work has been moved to the helper function,
vkms_composer_common() which is called by vkms_composer_worker()
and will be called in the implementation of virtual_hw mode
as well.

Changes
Add a virtual hardware or vblank-less mode as a module
to enable VKMS to emulate virtual hardware drivers. This means
no vertical blanking events occur and pageflips are completed
arbitrarily and when required for updating the frame.
Add a new drm_crtc_helper_funcs struct,
vkms_virtual_crtc_helper
