The sysfs_emit() function was introduced to make it less ambiguous which function is preferred when writing to the output buffer in a "show" callback [1]. Convert the I²C device sysfs interface from sprintf() to sysfs_emit() accordingly, as the latter is aware of the PAGE_SIZE buffer and correctly returns the number of bytes written into the buffer. No functional change intended.
