Subject: [PATCH v4 1/5] thermal: rockchip: improve conversion error messages
Date: Mon, 12 Dec 2016 19:05:31 +0800	[thread overview]
Message-ID: <1481540735-12710-2-git-send-email-wxt@rock-chips.com> (raw)
In-Reply-To: <1481540735-12710-1-git-send-email-wxt@rock-chips.com>

From: Brian Norris <briannorris@chromium.org>

These error messages don't give much information about what went wrong.
It would be nice, for one, to see what invalid temperature was being
requested when conversion fails. It's also good to return an error when
we can't handle a conversion properly.

While we're at it, fix the grammar too.

Changes in v1:
- The original Brian posted on https://patchwork.kernel.org/patch/9437686
  Note: it'd probably be even nicer to know which sensor this was, but we've
  kinda abstracted that one away by this point...
