initramfs: fix clang build failure
[ Upstream commit 55d5b7dd6451b58489ce384282ca5a4a289eb8d5 ]
There is only one function in init/initramfs.c that is in the .text
section, and it is marked __weak. When building with clang-12 and the
integrated assembler, this leads to a bug with recordmcount:
./scripts/recordmcount "init/initramfs.o"
Cannot find symbol for section 2: .text.
init/initramfs.o: failed
I'm not quite sure what exactly goes wrong, but I notice that this
function is only ever called from an __init function, and normally
inlined. Marking it __init as well is clearly correct and it leads to
recordmcount no longer complaining.
