kbuild: initramfs fix dependency checking for compressed target
When using initramfs compression, the data file compression suffix gets quotes pulled in from Kconfig, e.g., initramfs_data.cpio".gz" which make does not match a target and causes rebuild. Fix this by filtering out quotes from the Kconfig string. Fixes: 35e669e1a254 ("initramfs: select builtin initram compression algorithm on KConfig instead of Makefile") Reviewed-by: Francisco Blas Izquierdo Riera (klondike) <klondike@klondike.es> Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
