iio: light: fix improper return value
[ Upstream commit db4e5376d058af8924fafd0520a0942d92538d0e ]
In function cm3232_reg_init(), it returns 0 even if the last call to
i2c_smbus_write_byte_data() returns a negative value (indicates error).
As a result, the return value may be inconsistent with the execution
status, and the caller of cm3232_reg_init() will not be able to detect
the error. This patch fixes the bug.
