As per upstream commit 6992f5334995af474c2b58d010d08bc597f0f2fe,
"non-static sysfs attributes need to be initialized with
sysfs_attr_init or sysfs_bin_attr_init. Strictly speaking this
requirement only exists when lockdep is enabled, and when
lockdep is enabled we get a bit fat warning if this requirement is not met."
This patch adds the necessary function call in the qbman driver for
eliminating the warning.
