    Added Description In the Linux kernel, the following vulnerability has been resolved:

    clk: mmp2: call pm_genpd_init() only after genpd.name is set

    Setting the genpd’s struct device’s name with dev_set_name() is
    happening within pm_genpd_init(). If it remains NULL, things can blow up
    later, such as when crafting the devfs hierarchy for the power domain:

    Unable to handle kernel NULL pointer dereference at virtual address 00000000 when read
    …
    Call trace:
    strlen from start_creating+0x90/0x138
    start_creating from debugfs_create_dir+0x20/0x178
    debugfs_create_dir from genpd_debug_add.part.0+0x4c/0x144
    genpd_debug_add.part.0 from genpd_debug_init+0x74/0x90
    genpd_debug_init from do_one_initcall+0x5c/0x244
    do_one_initcall from kernel_init_freeable+0x19c/0x1f4
    kernel_init_freeable from kernel_init+0x1c/0x12c
    kernel_init from ret_from_fork+0x14/0x28

    Bisecting tracks this crash back to commit 899f44531fe6 (“pmdomain: core:
    Add GENPD_FLAG_DEV_NAME_FW flag”), which exchanges use of genpd->name
    with dev_name(&genpd->dev) in genpd_debug_add.part().
