In the Linux kernel, the following vulnerability has been resolved:

clk: rs9: Fix suspend/resume

Disabling the cache in commit 2ff4ba9e3702 ("clk: rs9: Fix I2C accessors")
without removing cache synchronization in resume path results in a
kernel panic as map->cache_ops is unset, due to REGCACHE_NONE.
Enable flat cache again to support resume again. num_reg_defaults_raw
is necessary to read the cache defaults from hardware. Some registers
are strapped in hardware and cannot be provided in software.
