[PATCH v3 RESEND2 1/1] staging: ion: debugfs invalid gfp mask

[Derek Yerger]

The current code attempts assignment of -1 to an unsigned type. Note that
in a downstream function ion_page_pool_shrink this mask is only ever
evaluated against __GFP_HIGHMEM
(drivers/staging/android/ion/ion_page_pool.c, line 125).
