Subject: [PATCH v2 net-next 5/6] net: aquantia: replace AQ_HW_WAIT_FOR with
readx_poll_timeout_atomic
From: Nikita Danilov <nikita.danilov@...antia.com>
David noticed the original define was hiding 'err' variable
reference. Thats confusing and counterintuitive.
Andrew noted the whole macro could be replaced with standard readx_poll
kernel macro. This makes code more readable.
