[PATCH] drm/nouveau: gk20a: Turn instmem lock into mutex
From: Thierry Reding <treding at nvidia.com>
The gk20a implementation of instance memory uses vmap()/vunmap() to map
memory regions into the kernel's virtual address space. These functions
may sleep, so protecting them by a spin lock is not safe. This triggers
a warning if the DEBUG_ATOMIC_SLEEP Kconfig option is enabled. Fix this
by using a mutex instead.
