Subject: [PATCH] hwrng: core: remove redundant initialization of variable ret
From: Colin Ian King <colin.king@...onical.com>
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.
Addresses-Coverity: ("Unused value")
