SDEI inherits the 'use hvc' bit that is also used by PSCI. PSCI does all its initialisation early, SDEI does its late. Remove the __init annotation from acpi_psci_use_hvc(). Signed-off-by: James Morse <james.morse@arm.com> Acked-by: Catalin Marinas <catalin.marinas@arm.com> --- The function name is unchanged as this bit is named 'PSCI_USE_HVC' in table 5-37 of ACPIv6.2. arch/arm64/kernel/acpi.c | 2 +- include/linux/psci.h | 3 ++- 2 files changed, 3 insertions(+), 2 deletions(-)
