   4 Subject: [PATCH 086/174] dwc_otg: fix potential sleep while atomic during urb
   5  enqueue
   6
   7 Fixes a regression introduced with eb1b482a. Kmalloc called from
   8 dwc_otg_hcd_qtd_add / dwc_otg_hcd_qtd_create did not always have
   9 the GPF_ATOMIC flag set. Force this flag when inside the larger
  10 critical section.
