Subject: drm/nouveau/secboot: remove nvkm_secboot_start()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c8225b54fe1b0d64b7da2c0d1d5b64d316b248f5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/nouveau/secboot: remove nvkm_secboot_start()

Since GR has moved to using the falcon library to start the falcons,
this function is not needed anymore.
