usb-storage: Correct adjust_quirks to include latest flags
Karl Relton [Wed, 18 May 2011 20:42:34 +0000 (21:42 +0100)]
Commits ae38c78a03e1b77ad45248fcf097e4568e740209
and 00914025cc4e783d4703b4db1d47b41f389e50c8 added quirk flags
US_FL_NO_READ_DISC_INFO and US_FL_NO_READ_CAPACITY_16 to
the usb-storage driver. However they did not add the corresponding flags
to adjust_quirks() in usb.c, so there was no facility for a user
to over-ride/add them via the quirks module parameter.
