Subject: [PATCH] grub-core/loader/efi/linux.c: drop now unused
|
|
grub_linuxefi_secure_validate
|
|
|
|
Drop the now unused grub_linuxefi_secure_validate() as all prior users
|
|
of this API now rely on the shim-lock-verifier codepath instead.
|
|
|
|
This patch must not be ported to older editions of grub code bases
|
|
that do not have verifiers framework, or it is not builtin, or
|
|
shim-lock-verifier is an optional module.
|
|
