lib: fix the use of LZO to decompress initramfs images
This patch fixes 2 issues with the LZO decompressor: - It doesn't handle the case where a block isn't compressed at all. In this case, calling lzo1x_decompress_safe will fail, so we need to just use memcpy() instead (the upstream LZO code does something similar) - Since commit 54291362d2a5738e1b0495df2abcb9e6b0563a3f ("initramfs: add missing decompressor error check") , the decompressor return code is checked in the init/initramfs.c The LZO decompressor didn't return the expected value, causing the initramfs code to falsely believe a decompression error occured Signed-off-by: Albin Tonnerre <albin.tonnerre@free-electrons.com> Tested-by: bert schulze <spambemyguest@googlemail.com> Cc: "H.
