[PATCH 1/1] drm/hyperv: Replace "hyperv_" with "hvdrm_" as symbol name prefix
From: Michael Kelley
Date: Tue May 26 2026 - 16:54:47 EST
From: Michael Kelley <mhklinux@xxxxxxxxxxx>
Function and structure names in the Hyper-V DRM driver currently
use "hyperv_" as the prefix. This conflicts with usage in core Hyper-V
and VMBus code, and incorrectly implies that functions and structures
in this driver apply generically to Hyper-V. A specific conflict arises
for "hyperv_init", which is an initcall for generic Hyper-V
initialization on arm64. The conflict prevents the use of
initcall_blacklist on the kernel boot line to skip loading this driver.
Fix this by substituting "hvdrm_" as the prefix for all functions and
structures in this driver. This prefix marries the existing "hv" prefix
for Hyper-V related code with "drm" to indicate this driver.
The changes are all mechanical text substitution in symbol names.
There are no other code or functional changes.
