The LINEAR modifier is advertised as default if a driver doesn't specify
modifiers. However, there are legacy drivers such as radeon that do not
support modifiers but infer the actual layout of the underlying buffer.
Therefore, a new flag not_support_fb_modifires is introduced for these
legacy driv
Some drivers whose planes only support linear layout fb do not support format
modifiers.
These drivers should support modifiers, however the DRM core should handle this
rather than open-coding in every driver.
In this patch series, these drivers expose format modifiers based on the
following sugge
Set fb_modifiers_not_supported flag in legacy drivers whose planes
support non-linear layouts but does not support modifiers, and replace
allow_fb_modifiers with fb_modifiers_not_supported.

In function nvkm_ioctl_map(), the variable "type" could be
uninitialized if "nvkm_object_map()" returns error code, however,
it does not check the return value and directly use the "type" in
the if statement, which is potentially unsafe.
