[PATCH v5 3/4] x86/boot/compressed: Declare immovable_mem index in loop initializer

[Thorsten Blum]

The for loop index i in process_mem_region() is unused when either
CONFIG_MEMORY_HOTREMOVE or CONFIG_ACPI is disabled. Declare it in the
for loop initializer to prepare for enabling unused-variable warnings.
