Subject: HID: extend autodetect to handle I2C sensors as well
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=fa79f5ec534eaae59a7cb2ca208178f03f9b75ec;p=linux-edison.git

HID: extend autodetect to handle I2C sensors as well

Since the advent of HID over I2C protocol, it is possible to have sensor
hubs behind I2C bus as well. We can autodetect this in a same way than USB
sensor hubs.
