gcc thinks that interpreting a multiplication result as a bool
is confusing:
drivers/gpu/drm/nouveau/nvkm/subdev/clk/gt215.c: In function 'read_pll':
drivers/gpu/drm/nouveau/nvkm/subdev/clk/gt215.c:133:8: error: '*' in boolean context, suggest '&&' instead [-Werror=int-in-bool-context]
In this instance, I think using multiplication is more intuitive
than '&&', so I'm adding a comparison to zero instead to shut up
the warning. To further improve readability, I also make the
error case indented and leave the normal case as the final 'return'
statement.
Fixes: 7632b30e4b8b ("drm/nouveau/clk: namespace + nvidia gpu names (no binary change)")
