[PATCH -next v2 0/3] cacheinfo: Fix misbehaviours around init_cache_level()

[Pierre Gondois]

v2:
https://lore.kernel.org/all/20230124123450.321852-1-pierre.gondois@arm.com/
- Split initial patch in 3.
- Add links to static-analysis reports.

Some cases were not correctly evaluated when updating
init_cache_level()'s prototype, in particular if CONFIG_ACPI_PPTT is
not defined. Fix them.

The initial diagnostic was done thanks to:
- the kernel test robot <lkp at intel.com>

Pierre Gondois (3):
  cacheinfo: Initialize variables in fetch_cache_info()
  cacheinfo: Make default acpi_get_cache_info() return an error
  cacheinfo: Remove unused check in init_cache_level()
