Subject: revert "initramfs: cleanup incomplete rootfs"
Revert ff1522bb7d9845 ("initramfs: cleanup incomplete rootfs").
Andy reports
: This breaks my setup where I have U-boot provided more size of initramfs
: than needed. This allows a bit of flexibility to increase or decrease
: initramfs compressed image without taking care of bootloader. The proper
: solution is to do this if we sure that we didn't get enough memory,
: otherwise I can't consider the error fatal to clean up rootfs.
Fixes: ff1522bb7d9845 ("initramfs: cleanup incomplete rootfs")
