Subject: hwrng: amd - remove redundant initialization of variable err
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b7c3635e56d6561436af59b9876faa7cc8389644;p=linux.git

hwrng: amd - remove redundant initialization of variable err

The variable err 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")
