X-Git-Tag: upstream/snapshot3+hdmi~12607^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=225d85fe7ddca2985548d98e410f7baf4a5d6260;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

mmc: sdhci: Allow the probe handler to override slots

Currently we write it to the chip data, but if the probe handler overrides
it we ignore the new value and keep using our cached one. Fix this so that
a probe handler can adjust the slot count.
