[dpdk-dev] [PATCH] usertools/devbind: fix binding for built-in kernel drivers

[Yongxin Liu]

In commit 681a67288 ("usertools: check if module is loaded before
binding"), script will exit if no driver is found in /sys/module/.

However, for build-in kernel driver, /sys/module/MODULENAME only
shows up if it has a version or at least one parameter. Take ixgbe
for example, after kernel commit 34a2a3b83e2c ("net/intel: remove
driver versions from Intel drivers"), and if ixgbe is built directly
into kernel, there is no ixgbe folder in /sys/module. So the devbind
script should not exit.
