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