Subject[PATCH 4.4 51/78] xhci: plat: Register shutdown for xhci_plat
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Adam Wallis <awallis@codeaurora.org>


[ Upstream commit b07c12517f2aed0add8ce18146bb426b14099392 ]

Shutdown should be called for xhci_plat devices especially for
situations where kexec might be used by stopping DMA
transactions.
