comp_desc') is related to commit 2bfa0719ac2 ('usb: gadget: function:

all stable branches where the latter exists, which include:
linux-4.11.y
linux-4.9.y
linux-4.4.y
linux-4.1.y
linux-3.18.y
Commit f3a511912a7b ('usb: gadget: f_fs: Fix possibe deadlock') fixes
an issue that exists in these branches (linux-4.11.y already contains
the change):
linux-4.9.y

linux-3.18.y
We've seen both issues on android-4.9 and android-4.4.
