Subject: [media] siano: use generic function to create MC device
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3d0ccad0dbbd51b64d307c64cc163002334afbfa;p=openwrt%2Fstaging%2Fblogic.git

[media] siano: use generic function to create MC device

Currently, it is initializing the driver name using the wrong
name ("usb"). Use the generic function, as its logic works
best, and avoids repeating the very same code everywhere.
