[PATCH 09/16] mmc: sdhci-xenon: use new match_string() helper/macro

From: Alexandru Ardelean
Date: Wed May 08 2019 - 07:31:21 EST


The change is also cosmetic, but it also does a tighter coupling between
the enums & the string values. This way, the ARRAY_SIZE(phy_types) that is
implicitly done in the match_string() macro is also a bit safer.
