Subject: [PATCH] tpm: svsm: constify tpm_chip_ops
Date: Tue,  5 May 2026 16:27:38 -0400	[thread overview]
Message-ID: <20260505202738.145800-1-dwindsor@gmail.com> (raw)

Constify the SVSM vTPM ops. It is statically initialized and never
written to, so let's store it in .rodata.

Every other tpm_class_ops instance in drivers/char/tpm/ is already
const.
