Subject: aoe: initialize sysminor to avoid compiler warning
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=10935d052eef9441a551571ff5853f84a00b2fd4;p=~shefty%2Frdma-dev.git

aoe: initialize sysminor to avoid compiler warning

Because the minor_get and related functions use the return values for
errors, the compiler doesn't know that sysminor will always either 1) be
initialized in aoedev_by_aoeaddr by the call to minor_get, or 2) be
unused as the "goto out" is executed.

This patch avoids the compiler warning.
