[RFC PATCH] mmc: Kconfig: Add dependency on GPIOLIB for Arasan driver

From: Michal Simek
Date: Fri Jul 24 2015 - 09:53:32 EST


The patch "mmc: sdhci-of-arasan: Call OF parsing for MMC"
(sha1: 16b23787fc709fe60c5d2bd05927b1a3da33d4e9) introduce new
dependency on GPIOLIB which calls mmc_of_parse() ->
mmc_gpiod_request_cd() (slot-gpio.c) which calls devm_gpiod_get_index()
which returns -ENOSYS.

Error log:
sdhci-arasan ff160000.sdhci: parsing dt failed (4294967258)
sdhci-arasan: probe of ff160000.sdhci failed with error -38

This problem is probably in all others drivers.
This is one way how this can be solved.
Maybe better way is to block return value for cd and wp.
