From: Michael Ellerman <mpe@xxxxxxxxxxxxxx> [ Upstream commit b36f835b636908e4122f2e17310b1dbc380a3b19 ] The lkp robot reported that some configs fail to build, for example mpc85xx_smp_defconfig, with: cc1: fatal error: opening output file arch/powerpc/boot/dts/fsl/.mpc8540ads.dtb.dts.tmp: No such file or directory This bisects to: cc8a51ca6f05 ("kbuild: always create directories of targets") Although that commit claims to be about in-tree builds, it somehow breaks out-of-tree builds. But presumably it's just exposing a latent bug in our Makefiles. We can fix it by adding to targets for dts/fsl in the same way that we do for dts.
