Subject: iio:ad5064: Make sure ad5064_i2c_write() returns 0 on success
From: Michael Hennerich <[email protected]>
commit 03fe472ef33b7f31fbd11d300dbb3fdab9c00fd4 upstream.
i2c_master_send() returns the number of bytes transferred on success while the ad5064 driver expects that the write() callback returns 0 on success. Fix that by translating any non negative return value of i2c_master_send() to 0.
