Subject: spi: Add "spi:" prefix to modalias attribute of spi devices
X-Git-Tag: upstream/snapshot3+hdmi~6968^2~11
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d8e328b3bd65fdefc9c49a27ee80c28e0a44b653;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

spi: Add "spi:" prefix to modalias attribute of spi devices

The modalias attribute of spi devices doesn't have the "spi:" prefix
that is used in the UEVENT and in spi device drivers.  This patch adds
the prefix so the modprobe can correctly match modules to devices.
