mfd: wm831x: Remove redundant !pdata checks
Since a copy of the pdata was added into the core struct in commit f6dd8449cd50 ("mfd: wm831x: Add basic device tree binding") the pdata pointer in probe can no longer be NULL. As such remove the redundant checks for this case. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
