Subject[ 028/149] cdc-wdm: Dont clear WDM_READ unless entire read buffer is emptied
3.2-stable review patch.  If anyone has any objections, please let me know.

------------------
From: Ben Hutchings <ben@decadent.org.uk>

commit b7a205545345578712611106b371538992e142ff upstream.

The WDM_READ flag is cleared later iff desc->length is reduced to 0.
