[PATCH 4.9 073/164] USB: chaoskey: fix Alea quirk on big-endian hosts

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

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

From: Johan Hovold <johan@xxxxxxxxxx>

commit 63afd5cc78775018ea2dec4004428dafa5283e93 upstream.

Add missing endianness conversion when applying the Alea timeout quirk.

Found using sparse:

	warning: restricted __le16 degrades to integer

Fixes: e4a886e811cd ("hwrng: chaoskey - Fix URB warning due to timeout on Alea")
