driver core: platform: remove redundant assignment to variable ret

Colin Ian King · gregkh · commit 45bb08de65b4 · 2020-04-23T17:04:22.000+02:00
The variable ret is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.
