powerpc/spufs: Fix refcount leak in spufs_init_isolated_loader

2022-08-01T12:21:18Z

of_find_node_by_path() returns remote device nodepointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.

powerpc: Add missing headers

2022-05-08T12:15:40Z

Don't inherit headers "by chances" from asm/prom.h, asm/mpc52xx.h, asm/pci.h etc... Include the needed headers, and remove asm/prom.h when it was needed exclusively for pulling necessary headers.

powerpc/spufs: adjust list element pointer type

2022-02-03T10:40:32Z

Other uses of &gang->aff_list_head, eg in spufs_assert_affinity, indicate that the list elements have type spu_context, not spu as used here. Change the type of tmp accordingly. This has no impact on the execution, because tmp is not used in the body of the loop.

powerpc/cell: Add __init attribute to eligible functions

2021-12-23T11:33:13Z

Some functions defined in 'arch/powerpc/platforms/cell' are deserving of an `__init` macro attribute. These functions are only called by other initialization functions and therefore should inherit the attribute.
