Commit 35e669e1a254 ("initramfs: select builtin initram compression algorithm on KConfig instead of Makefile") makes suffix_y be a quote variable, which can be illustrated looking at the build output:
GEN usr/initramfs_data.cpio".gz" Make sure that we do strip off double quotes from CONFIG_INITRAMFS_COMPRESSION, since the Makefile tracks targets with unquoted suffixes.
