5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>
commit 1db4da55070d6a2754efeb3743f5312fc32f5961 upstream.
In accordance with the existing comment and code analysis
it is quite likely that there is a missed 'else' when adapter
times out. Add it.
Fixes: 5bc1200852c3 ("i2c: Add Intel SCH SMBus support")
