mainline inclusion from mainline-v5.13-rc1 commit 95c612b30898ca5fe7c76ef31d910e37ace6f34e category: feature bugzilla: 173981 CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
The Kunpeng930 changes some field meanings in 'sqe'. So add a new 'hisi_zip_sqe_ops' to describe the 'sqe' operations.
