Subject: [PATCH] leds: is31fl32xx: Fix missing error code in is31fl32xx_parse_dt()

The error code is missing in this code scenario, add the error code
'-EINVAL' to the return value 'ret'.

Eliminate the follow smatch warning:

drivers/leds/leds-is31fl32xx.c:388 is31fl32xx_parse_dt() warn: missing
error code 'ret'.
