kbuild: clean compressed initramfs image
[ Upstream commit 6279eb3dd7946c69346a3b98473ed13d3a44adb5 ] Since 9e3596b0c653 ("kbuild: initramfs cleanup, set target from Kconfig") "make clean" leaves behind compressed initramfs images. Example: $ make defconfig $ sed -i 's|CONFIG_INITRAMFS_SOURCE=""|CONFIG_INITRAMFS_SOURCE="/tmp/ir.cpio"|' .config $ make olddefconfig $ make -s $ make -s clean $ git clean -ndxf | grep initramfs Would remove usr/initramfs_data.cpio.gz clean rules do not have CONFIG_* context so they do not know which compression format was used. Thus they don't know which files to delete. Tell clean to delete all possible compression formats. Once patched usr/initramfs_data.cpio.gz and friends are deleted by "make clean".
