Subject: [PATCH 4.8 68/92] rtc: pcf2123: Add missing error code assignment before test

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

commit 83ab7dad06b74e390c2ce0e7b5136daf286e1f5e upstream.

It is likely that checking the result of 'pcf2123_write_reg' is expected
here.
Also fix a small style issue. The '{' at the beginning of the function
is misplaced.
