Subject: [PATCH v2 0/5] regcache: Avoid accessing non-initialised cache
Date: Wed, 25 Feb 2026 17:15:54 +0100 [thread overview]
Message-ID: <20260225161659.3811671-1-andriy.shevchenko@linux.intel.com> (raw)
Refactor regcache flow that populates cache on initialisation phase
based on the values in HW. This makes code robust against any possible
accesses to not-fully initialised caches.
Changelog v2:
- rebased on top of the latest regmap changes (Mark)
- added two more little cleanups (patches 4 & 5)
Andy Shevchenko (5):
regcache: Remove duplicate check in regcache_hw_init()
regcache: Split regcache_count_cacheable_registers() helper
regcache: Move HW readback after cache initialisation
regcache: Define iterator inside for-loop and align their types
regcache: Amend printf() specifiers when printing registers
