If anyone has any objections, please let me know. ------------------ From: Marek Szyprowski [ Upstream commit 97aee67e2406ea381408915e606c5f86448f3949 ] Commit 8c3170628a9c ("wifi: brcmfmac: keep power during suspend if board requires it") changed default behavior of the BRCMFMAC driver, which now keeps SDIO card powered during system suspend to enable optional support for WOWL. This feature is not supported by the legacy Exynos4 based boards and leads to WLAN disfunction after system suspend/resume cycle. Fix this by annotating SDIO host used by WLAN chip with 'cap-power-off-card' property, which should have been there from the beginning.
