Subject: gpu: nova-core: use correct fwsignature for GA100
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c1dca0cb0e761568c448a6007855fe5879ad4d37;p=thirdparty%2Fkernel%2Flinux.git

gpu: nova-core: use correct fwsignature for GA100

Although GA100 uses the same GSP-RM firmware as Turing, it has a different
signature specifically for it.
