Subject: USB: opticon: fix non-atomic allocation in write path
From: Johan Hovold <johan@xxxxxxxxxx>
commit e681286de221af78fc85db9222b6a203148c005a upstream.
Write may be called from interrupt context so make sure to use
GFP_ATOMIC for all allocations in write.
Fixes: 0d930e51cfe6 ("USB: opticon: Add Opticon OPN2001 write support")
