Subject: hwrng: core - remove redundant initialization of variable ret
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=45645709704f94d2625ef15fbf7bcae51aeab975;p=linux.git

hwrng: core - remove redundant initialization of variable ret

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")
