Subject: mmc: sdhci: Report failure reasons for all cases in sdhci_add_host()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0fc81ee3102efedd4571e28372d2242c694c67ec;p=openwrt%2Fstaging%2Fblogic.git

mmc: sdhci: Report failure reasons for all cases in sdhci_add_host()

For most error conditions sdhci_add_host() will print a diagnostic
message indicating why it failed but there are a few cases where this
does not happen. Add error messages in these cases to aid diagnosis.
