This set addresses two issues one a contrived but real corner-case crash scenario and the other a simple typo.
Debugging on a QCS405 which has an ath10k attached to PCIe its been found that a loop similar to the below [1] will cause. 1. A significant slow-down in the time it takes an individual ioread32() to complete. 2. A secure watchdog bite. This is as a result of the restart routine and the dump register routine running in parallel and a period of time during restart where dumping registers is unstable. The second patch is a simple fix to an apparent copy/paste error describing the behavior of a similar dump function.
