    Subject[PATCH 5.10 501/717] powerpc/boot: Fix build of dts/fsl
    Date
    From: Michael Ellerman <mpe@ellerman.id.au>

    [ 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.

    Fixes: cc8a51ca6f05 ("kbuild: always create directories of targets")
