[PATCH 14/19] staging: iio: isl29028: move failure logging into isl29028_set_als_scale()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When isl29028_set_als_scale() fails, it was up to both callers to log
the failure message. This patch moves the logging into
isl29028_set_als_scale() to reduce the overall amount of code in the
driver.
