Subject: sh: ecovec24: Use MMC/SDHI CD and RO GPIO
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=afa2c9407f8908e2269b243773cbb0997c553804;p=linux-beck.git

sh: ecovec24: Use MMC/SDHI CD and RO GPIO

Pass the CD and RO GPIO numbers to the MMC SPI and SDHI drivers and
remove the custom .get_cd() and .get_ro() callback functions.
