mfd/asic3: fix asic3_mfd_probe return value
In commit 4f304245b "mfd: Set asic3 DS1WM clock_rate", a possible path through asic3_mfd_probe was introduced that would lead to an unpredictable return value, if everything succeeds but there are pdata->leds is NULL. This was reported correctly by gcc. Without this patch, building magician_defconfig results in: drivers/mfd/asic3.c: In function 'asic3_mfd_probe': drivers/mfd/asic3.c:940:2: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Paul Parsons <lost.distance@yahoo.com> Cc: Philipp Zabel <philipp.zabel@gmail.com> Cc: Samuel Ortiz <sameo@linux.intel.com>
