[PATCH] staging/ks7010: Fix type assignment for struct hostif_hdr

From: Cezary Gapinski
Date: Sat Apr 29 2017 - 13:54:58 EST


Sparse spits out a warnings about __le16 and unsigned short assignment.
Change the type of size and event members of struct hostif_hdr
to __le16 and correct conversion to the proper cpu type.
