Subject: [PATCH 0/6] first step of standardising OPAL_BUSY handling
Date: Thu, 5 Apr 2018 18:15:41 +1000 [thread overview]
Message-ID: <20180405081547.13266-1-npiggin@gmail.com> (raw)
Patch 1 explains most of the reasoning.
Patch 1+2 and possibly 4 (just that we've seen a bug caused by the
RTC driver but not yet one caused by NVRAM) could be backported as
bugfixes, in most other cases the changes are inconsequential or
unlikely to be a problem.
Thanks,
Nick
