Subject: [PATCH] drivers/rtc/rtc-isl12057.c: report error code upon failure in
 dev_err() calls
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

As pointed out by Mark, it is generally useful to log the error code when
reporting a failure.  This patch improves existing calls to dev_err() in
ISL12057 driver to also report error code.
