* powerpc/8xx: add __init to cpm1 init functionsChristophe Leroy2019-11-191-1/+1
| | | | | | | | | | Functions cpm1_clk_setup(), cpm1_set_pin(), cpm_pic_init() and mpc8xx_pic_init() are only called from __init functions, so mark them __init as well.

* powerpc/8xx: Fix possible device node reference leakWen Yang2019-04-201-2/+1
| | | | | | | | | | | | | | | | | | | The call to of_find_compatible_node() returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. irq_domain_add_linear() also calls of_node_get() to increase refcount, so irq_domain() will not be affected when it is released. Detected by coccinelle.
