nouveau nvaa clock missing break?

Hi,

Just curious if this code is missing a "break" or not...

/drivers/gpu/drm/nouveau/core/subdev/clock/nvaa.c: 373 in nvaa_clock_prog()

switch (priv->vsrc) {
case nv_clk_src_cclk:
mast |= 0x00400000;
default:
nv_wr32(clk, 0x4600, priv->vdiv);
}

Coverity noticed it as CID 1135671. If it's intentional, it might be
nice to add a "fall through" comment there.

Coverity also complained about read_pll (CID 1135670) where post_div
could (unlikely) be 0 and used for a divide-by-zero.

Thanks!

-Kees
