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