Remove ghes_register_vendor_record_notifier() and ghes_unregister_vendor_record_notifier() along with their EXPORT_SYMBOL_GPL()s and ghes.h declarations, since there are no remaining in-tree callers — all users go through devm_ghes_register_vendor_record_notifier() instead. Inline the register/unregister calls directly into devm_ghes_register_vendor_record_notifier() and its destroy callback. Signed-off-by: Eliav Farber <redacted> Reviewed-by: Jonathan Cameron <redacted> --- Changes in v4: - Split from the devm conversion patch into its own commit (Andy Shevchenko) Changes in v2: - New patch: remove unused ghes_register_vendor_record_notifier() and ghes_unregister_vendor_record_notifier() along with their EXPORT_SYMBOL_GPL()s and ghes.h declarations, since there are no in-tree callers (Jonathan Cameron) drivers/acpi/apei/ghes.c | 16 +++------------- include/acpi/ghes.h | 16 ---------------- 2 files changed, 3 insertions(+), 29 deletions(-)
