From 2c247804796bbcaa90087f2196f68fdc20a5fe04 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Wed, 11 Mar 2015 10:00:05 -0500 Subject: Revert "usb: gadget: zero: Add support for interrupt EP" This reverts commit ef11982dd7a657512c362242508bb4021e0d67b6. That commit creates a problem for some UDCs (at least musb) where it allocates an endpoints with a 64-byte FIFO, but later tries to use that same FIFO for 1024-byte packets. Before implementing this, composite framework needs to be modified so we only allocate endpoints after we know negotiated speed, however that needs quite a bit of extra work.
