Subject: virtio_blk: Delete an unnecessary initialisation in init_vq()
X-Git-Url: http://git.cascardo.info/?p=cascardo%2Flinux.git;a=commitdiff_plain;h=2ff98449ee883d6e7484f5937370df42d6789e07

virtio_blk: Delete an unnecessary initialisation in init_vq()

The local variable "err" will be set to an appropriate value
by a following statement.
Thus omit the explicit initialisation at the beginning.
