spi: spl022: fix sleeping in interrupt context

Merge series from Nam Cao <namcao@linutronix.de>: While running the spl022, I got the following warning: BUG: sleeping function called from invalid context at drivers/spi/spi.c:1428 This is because between spi transfers, spi_transfer_delay_exec() (who may sleep if the delay is >10us) is called in interrupt context. This is a problem for anyone who runs this driver and need more than 10us delay. Patch 1 adds an error reporting mechanism, needed by patch 2 who switch to use the default spi_transfer_one_message(), which fix the problem. The series is tested with polling transfer mode and interrupt transfer mode. I can't test the DMA mode, so some help testing here is very appreciated.

 Generally speaking, the patches get triaged quickly (in less than
 48h). But be patient, if your patch is active in patchwork (i.e. it's
 listed on the project's patch list) the chances it was missed are close to zero.
-Asking the maintainer for status updates on your
-patch is a good way to ensure your patch is ignored or pushed to the
-bottom of the priority list.
+
+The high volume of development on netdev makes reviewers move on
+from discussions relatively quickly. New comments and replies
+are very unlikely to arrive after a week of silence. If a patch
+is no longer active in patchwork and the thread went idle for more
+than a week - clarify the next steps and/or post the next version.
+
+For RFC postings specifically, if nobody responded in a week - reviewers
+either missed the posting or have no strong opinions. If the code is ready,
+repost as a PATCH.
+
+Emails saying just "ping" or "bump" are considered rude. If you can't figure
+out the status of the patch from patchwork or where the discussion has
+landed - describe your best guess and ask if it's correct. For example::
+
+  I don't understand what the next steps are. Person X seems to be unhappy
+  with A, should I do B and repost the patches?
