[PATCH] spi: amlogic: Fix error checking on regmap_write call

[Colin Ian King]

Currently a call to regmap_write is not being error checked because the
return checke is being performed on the variable ret and this variable
is not assigned the return value from the regmap_write call. Fix this
by adding in the missing assignment.
