Subject: [GIT PULL] bzip2/lzma Kconfig warning fix

Hi Linus,

This patch should take care of the annoying Kconfig warning from the
bzip2/lzma code.

The following changes since commit 15f7176eb1cccec0a332541285ee752b935c1c85:

    bzip2/lzma: quiet Kconfig warning for INITRAMFS_COMPRESSION_NONE
    
    Impact: quiet Kconfig warning
    
    It appears that Kconfig simply has no way to provide defaults for
    entries that exist inside a conditionalized choice block.
    Fortunately, it turns out we don't actually ever use
    CONFIG_INITRAMFS_COMPRESSION_NONE, so we can just drop it for
    everything outside the choice block.
