Subject: gpu: nova-core: Replace module_pci_driver! with explicit module init
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ea0c83806f790de0b3441ddebbbcfd82196d6cce;p=thirdparty%2Fkernel%2Fstable.git

gpu: nova-core: Replace module_pci_driver! with explicit module init

Replace the module_pci_driver! macro with an explicit module
initialization using the standard module! macro and InPlaceModule
trait implementation.  No functional change intended, with the
exception that the driver now prints a message when loaded.

This change is necessary so that we can create a top-level "nova_core"
debugfs entry when the driver is loaded.
