[PATCH v1 0/3] regcache: Avoid accessing non-initialised cache

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

FIXME cover letter

Some caches may not allow writes before full initialisation is done.
In particular on REGMAP_MAPLE caches when we want to populate cache
with the values (reg_defaults_raw == NULL && num_reg_defaults_raw != 0)
from HW, the NULL pointer dereference may happen. Address this by moving
the IO after cache initialisation is done.

Andy Shevchenko (3):
  regcache: Remove duplicate check in regcache_hw_init()
  regcache: Split regcache_count_cacheable_registers() helper
  regcache: Move HW readback after cache initialisation
