Subject: efi/libstub: Cast away type warning in use of max()
Origin: https://git.kernel.org/pub/scm/linux/kernel/git/efi/efi.git/commit?id=07263d8a5a2cea66a3f10d930fea60ce49c7dc3b
Add a missing (u64) cast to alloc_min, which is passed into
efi_random_alloc() as unsigned long, while efi_physical_addr_t is u64.
Fixes: 3cb4a4827596abc82e ("efi/libstub: fix efi_random_alloc() ...")
