Subject: [PATCH 4.2.y-ckt 151/211] DT: mmc: sh_mmcif: fix "compatible" property text

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sergei Shtylyov <sergei.shtylyov@...entembedded.com>

commit 76d63c2b59d4a1481bedc65a3ef25e9d1354dca3 upstream.

The "compatible" property text contradicts even the example given in the MMCIF
binding document itself;  moreover, the Renesas MMCIF driver only matches  on
the generic "compatible" string and doesn't look for the SoC specific strings
at all. Thus describe "renesas,sh-mmcif" as a fallback value.
