Subject: usb: Auto-load cdc_acm module when device opened.
X-Git-Tag: upstream/snapshot3+hdmi~19423
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e766aeb882b41355d8732cf49aa9412baef852c5;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

usb: Auto-load cdc_acm module when device opened.

The cdc_acm module is missing the char-major-166-* alias that would
cause it to be auto-loaded when a device of that type is opened.  This
patch adds the alias.
